Re: [CentOS] Troubles expanding file system. - Solved
tem is now 183500446 blocks long. 6. Remount the filesystem and check the filesystem size. sequoia# mount /dev/vde1 /ecosystem sequoia# service smb start sequoia# df -h filesystem=/dev/vde1 size=689G used=459G available=196G used%=71% mount=/ecosystem 7. So in conclusion I needed to do the following steps to resize and expand my disk without a reboot. There may still be other ways that this can be accomplished, but this worked for my CentOS 6 system (both host and guest). a. On the host system, lvextend to expand the logical volume used by the guest as it's disk. b. On the host system, virsh blockresize to get the guest system to recognize the expanded disk space. c. On the guest system, growpart to grow the partition to the expanded space. d. On the guest system, unmount the filesystem (stop services as required). e. On the guest system, partprobe to get the kernel to recognize the expanded partition. f. On the guest system, resize2fs (run filesystem check if required) to expand the filesystem. Thanks to all that provided suggestions and insight, it was very helpful in my research and methodical stepping through this process.

Re: [CentOS] Troubles expanding file system.
I realized I was still on receiving the daily digest format last night, so I have probably screwed up the threading on this now. If you cc me directly maybe I can maintain the future threading. Ok, looking at Parted it looks like the resize (or resizepart) command will be what I will need. But that doesn't appear to help recognize the expanded disk, so I think I need something before that. That is what I thought the echo 1 > rescan would do for me. I will look more into fdisk to understand the capabilities there. I am going to take advantage of the holiday weekend in a few days to take care of this so I am trying to understand all of the options available to me before diving into the task. In response to Gordon also, I did rescan the drive as suggested and got the same results; no such file or directory. So then I did a search for the rescan file to see where it was present. Found it in a few locations, but this one looks to be the one that I would want to try. /sys/devices/pci:00/:00:01.1/host1/target1:0:0/1:0:0:0/ The rescan file was also located in just: /sys/bus/pci but don't know if that would do the job for the specific device. Thanks for everyone's input. Very helpful. More suggestions are welcome while I am still reading up on options.

[CentOS] How to block routing/forwarding with firewalld
On CentOS 7 with firewalld I have a box with numerous interfaces acting as a NAT gateway. This works but I noticed that it routes/forwards traffic not just from my internal zone to external zone but also between interfaces within the internal zone. How can I prevent that traffic? I've tried adding direct and rich rules to deny the traffic but it doesn't work. Direct: firewall-cmd --direct --add-rule ipv4 filter INPUT 0 -s 10.110.4.0/22 -d 10.110.0.0/22 -j REJECT That command works, and I see it in `iptables -L` but traffic is still allowed.

[CentOS] Kernel version in CentOS 7 pxeboot images
I have a number of machines which PXE boot using the images provided by CentOS here: http://mirror.centos.org/centos/7/os/x86_64/images/pxeboot/ That gives the machines kernel 3.10.0-327.el7.x86_64. I would like to move to a newer kernel as I'm seeing a serious I/O problem which I suspect is a kernel bug. I thought that would be as easy as grabbing the files from here: http://mirror.centos.org/centos/7.2.1511/os/x86_64/images/pxeboot/ ... but that's not the case, those are the same exact files as the earlier ones. These machines always PXE boot, they have no OS installed to their local disk. Instead their root filesystem is on an NFS server. So this is not PXE+kickstart or other provisioning system, just PXE then mount an NFS export for its root filesystem. So, how would one go about creating a new vmlinuz and initrd.img the same way that the ones shown above were built, except with a newer kernel?

[CentOS] Incoming rsync connection attempts
Greetings - In my logwatch report this morning I noticed reference to an attempt to connect to rsync from an external IP address. It doesn't appear that the connection was successful based on correlating information between /var/log/secure and /var/log/messages. But I am looking for some suggestions for implementing more preventative measures, if necessary.

I will retire it when it dies, until then it runs fairly maintenance free. I do have a public IP address assigned to the WAN because we have a vsftp server running on it for transferring files back and forth to a few clients, and I occasionally access the server remotely.

[CentOS] Issue getting Gnome display manager on Centos 6 to Xming on Win7
Greetings - My objective is to get a full Gnome GUI console display to show in an Xming window on my Win7 box. I do a similar thing with my Raspberry Pi so that it operates headless with just the power and network cord attached. My CentOS 6 box and the Win7 box are on the same network within my office LAN behind a good firewall. For various reasons that I won't go into I am unable to combine them into a single box using KVM, so I would at least like to be able to display my CentOS Gnome GUI within an Xming window on my Win7 box. And I like the way that Xming works, so I would rather not switch to something like X2Go as I wasn't too keen on it when I last tried it. I have done plenty of research on the web that describes how to do this, but I must be missing something. I have the following things configured on the CentOS 6 box. /etc/gdm/custom.conf file [security] DisallowTCP=false AllowRemoteRoot=true [xdmcp] Enable=true /etc/ssh/sshd_config X11Forwarding yes X11DisplayOffset 10 X11UseLocalHost yes I start Xming on the Win7 box with the basic parameters. Xming.exe :0 -resize -clipboard (one window is default) Putty has X11 Forwarding enabled. After logging into the CentOS box via Putty I can invoke a single program, such as Gedit and it will display on the Xming window, but I can not seem to get the entire Gnome GUI display manager. On my Raspberry Pi, once logged in through Putty I just type "startlxde" at the command prompt to get the entire display. But the Pi is a Debian based system running a different display manager, so I don't know what would be comparable for CentOS 6, and whether additional configuration is needed. I have tried all the basic troubleshooting actions. I have disabled the firewalls on both the CentOS 6 and Win7 boxes, and I have changed SELinux to permissive mode. None of these changes made any difference, I could still display Gedit but not the entire Gnome GUI display manager. So I figure there must be something else I need to do that I am not finding in all my Google searches. Can someone clue me in please. Thanks.

[CentOS] General question about understanding PCI passthrough
Greetings - I saw Andrew Holway's post yesterday referencing using PCI passthrough as a solution to someone else's issue. Not being familiar with it, the post made me look into it more to see if it is something to use for my setup. From my research on the web, I have two questions to make sure I understand how PCI passthrough works. 1. If you use PCI passthrough on a graphics card to allow a virtual guest direct access to the graphics card for it use, does the host still have use of the graphics card also? 2. Or, once you pass it to the guest, the host can then no longer use it and has to rely on base level motherboard graphics? It looks from my reading that using PCI passthrough you can make the graphics card available to multiple guest simultaneously, but it seemed to imply that the host could no longer use it. With the box that I am configuring, I was planning on installing Linux Mint (Cinnamon Desktop) as my kvm host, then installing Win7 as a virtual guest. Since I use some mapping software in Win7 it would be nice to be able to use the graphics card via PCI passthrough, but not at the expense of loosing it from the Mint Cinnamon Desktop. However if multiple kvm guests can use the graphics card simultaneously (but the host can not), the maybe I should use CentOS as a very basic host and then make both Mint and Win7 guests.

[CentOS] Centos 7 how to make second disk of RAID1 bootable
Greetings - Ok, I have my CentOS 7 KVM host system installed and I want to be able to boot the system from either installed drive if one of them fails. My objective is to have the following layout for the two 3 TB disks. sda1 /boot/efi sda2 /boot sda3 RAID1 with sdb3 sdb1 /boot/efi sdb2 /boot sdb3 RAID1 with sda3 The system is installed and boots from sda[1,2] and md127 (sda3 and sdb3). sdb[1,2] were untouched during the installation, and had been partitioned as FAT32 prior to the installation exactly the same as sda[1,2] using GParted. A GPT partition table was added to both disks before partitioning. The current partition information for my two drives is: Disk /dev/sda: 5860533168 sectors, 2.7 TiB Logical sector size: 512 bytes Disk identifier (GUID): 0C26A36C-3857-4E97-85CC-2D4E57F4015A Partition table holds up to 128 entries First usable sector is 34, last usable sector is 5860533134 Partitions will be aligned on 2048-sector boundaries Total free space is 2925 sectors (1.4 MiB) Number Start (sector) End (sector) Size Code Name 1 2048 1026047 500.0 MiB EF00 EFI System Partition 2 1026048 2050047 500.0 MiB 0700 3 2050048 5860532223 2.7 TiB FD00 Disk /dev/sdb: 5860533168 sectors, 2.7 TiB Logical sector size: 512 bytes Disk identifier (GUID): A3F0F6C1-A395-4A24-8940-BDE803E5D073 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 5860533134 Partitions will be aligned on 2048-sector boundaries Total free space is 2925 sectors (1.4 MiB) Number Start (sector) End (sector) Size Code Name 1 2048 1026047 500.0 MiB 0700 2 1026048 2050047 500.0 MiB 0700 3 2050048 5860532223 2.7 TiB FD00 sda1 and sda2 were reformatted during installation; with sda1 showing in GParted now as FAT16 and a boot flag, and sda2 showing as XFS without a boot flag. sdb[1,2] still show as FAT32 and have no files on them. What is the simplest and least error-prone way to make my second drive (sdb) bootable if the first drive (sda) were to fail? I have done a lot of Googling over the last few days to try and understand what needs to be done, and almost everything I find is outdated in that it does not reference using grub2, and does not reference UEFI booting. I am open to reading more how-to's if someone knows of a good one that I may have missed in the 50 plus guides I have looked at. I suspect that this is really not that difficult, but the detail that I need seems to be missing in what I have read. Any responses may cc me directly as I only get the daily digest. Thanks.

I initially created the sda[1,2] and sdb[1,2] partitions via GParted leaving the remaining space unpartitioned. I'm pretty sure that's not necessary. I've been able to simply change the device type to RAID in the installer and get mirrored partitions. If you do your setup entirely in Anaconda, your partitions should all end up fine. It may not be absolutely necessary, but it appears to me to be the only way to get to my objective. The /boot/efi has to be on a separate partition, and it can not be on a RAID device. The /boot can be on LVM according to the documentation I have seen, but Anaconda will give you an error and not proceed if it is. Someone pointed this out to me a few days ago, that this is by design in RH and CentOS. And within the installer I could not find a way to put /boot on a non-LVM RAID1 while the rest of my drive is setup with LVM RAID1. So that is when I went to GParted to manually setup the /boot/efi and /boot partitions before running the installer. At this point I needed to copy my /boot/efi and /boot partitions from sda[1,2] to sdb[1,2] so that the system would boot from either drive, so I issued the following sgdisk commands: root# sgdisk -R /dev/sdb1 /dev/sda1 root# sgdisk -R /dev/sdb2 /dev/sda2 root# sgdisk -G /dev/sdb1 root# sgdisk -G /dev/sdb2 sgdisk manipulates GPT, so you run it on the disk, not on individual partitions. What you've done simply scrambled information in sdb1 and sdb2. The correct way to run it would be # sgdisk -R /dev/sdb /dev/sda # sgdisk -G /dev/sdb Point taken, I am going back to read the sgdisk documentation again. I had assumed that this would be a more technically accurate way to copy sda[1,2] to sdb[1,2] rather than using dd as a lot of how-to's suggest. However, you would only do that if sdb were completly unpartitioned. As you had already made at least one partition on sdb a member of a RAID1 set, you should not do either of those things. The entire premise of what you're attempting is flawed. Making a partition into a RAID member is destructive. mdadm writes its metadata inside of the member partition. The only safe way to convert a filesystem is to back up its contents, create the RAID set, format the RAID volume, and restore the backup. Especially with UEFI, there are a variety of ways that can fail. Just set up the RAID sets in the installer. I need some additional explanation of what you are trying to say here, as I don't understand it. My objective is to have the following layout for my two 3TB disks. sda1/boot/efi sda2/boot sda3RAID1 with sdb3 sdb1/boot/efi sdb2/boot sdb3RAID1 with sda3 I just finished re-installing using my GParted prepartitioned layout and I have a bootable system with sda1 and sda2 mounted, and md127 created from sda3 and sdb3. My array is actively resyncing, and I have successfully rebooted a couple of times without a problem. My goal now it to make sdb bootable for the case when/if sda fails. This is the process that I now believe I failed on previously, and it likely has to do with issueing the sgdisk command to a partition rather than a device. But even so, I don't understand why it would have messed with my first device that had been bootable. I then installed GRUB2 on /dev/sdb1 using the following command: root# grub2-install /dev/sdb1 Results: Installing for x86_64-efi platform. Installation finished. No error reported. Again, you can do that, but it's not what you wanted to do. GRUB2 is normally installed on the drive itself, unless there's a chain loader that will load it from the partition where you've installed it. You wanted to: # grub2-install /dev/sdb Yes, I am beginning to think this is correct, and as mentioned above am going back to re-read the sgdisk documentation. I rebooted the system now, only to be confronted with a GRUB prompt. I'm guessing that you also constructed RAID1 volumes before rebooting, since you probably wouldn't install GRUB2 until you did so, and doing so would explain why GRUB can't find its configuration file (the filesystem has been damaged), and why GRUB shows "no known filesystem detected" on the first partition of hd1. If so, that's expected. You can't convert a partition in-place. Looking through the directories, I see that there is no grub.cfg file. It woul

Thinking that this is a good opportunity to for me to learn to rescue a system since I am going to need to understand how to recover from a disk or raid failure, I started researching and reading. It takes a little bit of work to understand what information is valuable when a lot of it refers to GRUB (not GRUB2) and doesn't make reference to UEFI booting and partitions. I found this Ubuntu wiki as a pretty good source https://help.ubuntu.com/community/Grub2/Troubleshooting#Search_.26_Set I found the upstream documentation for grub2 to be useful: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/ch-Working_with_the_GRUB_2_Boot_Loader.html Included is a procedure for completely reinstalling grub2 which might help you recover. . . . trim . . . Ned, thanks for your insight. I feel like I have been sleeping with that RH7 document the last day or so trying to understand what I messed up and how to recover, I just didn't reference it in my post. Your conclusion about grub2-install being directed to the partition rather than the device may be correct, and is about the only little detail that I see that may have been wrong. The weird thing is that the installation should have put everything in the proper place on the primary drive, and my grub2-install command is being directed at putting it on the secondary drive. That is what is confusing me as the proper grub files should have been on the primary drive, allowing me to boot from there. It would have been nice if I had happened to check for the grub files before the failed reboot, or immediately after the installation. I think at this point I am going to not try and recover, but just re-install from scratch. I have gained enough knowledge in the past few days learning about grub that at least I know the general process and how to get started, but at this point I want to make sure I have a good clean system on the initial install.

[CentOS] CentOS 7 grub.cfg missing on new install
ch-root.service. Starting Emergency Shell. . . Failed to issue method call: Invalid argument Now I am not sure that I want to get misdirected to what the problem is with this boot, if I can boot from a CD in linux rescue mode and do the grub install, then be back to a booting system. So lets ignore the boot error if we can. So I boot from a CD in rescue mode, and it is only able to automatically mount sd3 under /mnt/sysimage (the LVM RAID1 containing mounts for / and /var). I am able to manually mount sda1 and sda2, but am not sure at what level in the filesystem to mount them (i.e., at /mnt/sda1 or at mnt/sysimage/sda1) in order to properly run grub2-install. So that is where I am at now. I would like to know how to repair the system, rather than starting over on a new install. Can someone enlighten me on what I need to do from here. Also if someone can speculate on why my grub.cfg is missing in the first place I would be interested. Also, please cc me directly on any responses, as I am only subscribed to the daily digest.

The options within the installer then appear to allow me to create my LVM with Raid1, but the /boot and /boot/efi are then outside the Raid. 4. It looks like I can set the /boot partition to be Raid1, but then it is a separate Raid1 from the LVM Raid1 on the rest of the disk. Resulting in two separate Raid1s; a small Raid1 for /boot and a much larger Raid1 for the LVM volume group. I finally manually setup a base partition structure using GParted that allowed the install to complete using the format below. sda (3TB) sda1 /boot fat32 500MB sda2 /boot/efi fat32 500MB sdb (3TB) sdb1 /boot fat32 500MB sdb2 /boot/efi fat32 500MB The remaining space was left unpartitioned in GParted, which was then prepared as LVM Raid1 in the CentOS installer. The installer also put the /boot and /boot/efi files on sda1 and sda2. Then I would have to manually copy them over to sdb1 and sdb2 if I wanted to be able to boot from drive sdb if drive sda failed. I am not sure that this result is what I really want, as it doesn't Raid my entire drives. The structure below is what I believe I want to have. sda & sdb RAID1 to produce md1 md1 partitioned md1a /boot non-LVM md1b /boot/efi non-LVM md1c-f LVM containing /, /var, /home, and /swap Well the abbreviations may not be the proper syntax, but you probably get the idea of where I am going. If this is correct, then it looks like I need to create the RAID from the command line of a rescue disk and set the /boot and /boot/efi partitions first before beginning the installer. But then again I could be totally off the mark here so I am looking for someone to set me straight. Thanks. Jeff The last time I actually needed to do this was probably Centos 5, so someone will correct me if I have not kept up with all the changes. 1. Even though GRUB2 is capable of booting off of an LVM drive, that capability is disabled in RHEL & Centos. Apparently RH doesn't feel it is mature yet. Therefore, you need the separate boot partition. (I have a computer running a non-RH grub2 installation, and it boots off of LVM OK, but apparently it falls into the "works for me" category). Now that you say that I do recall seeing someone mention that before on this list, but had not run across it recently in all my Goggle searching. 2. I cannot comment from experience about the separate drive for /boot/efi, but needing a separate partition surprises me. I have not read about others needing that. I would think that having an accessible /boot partition would suffice. I tried a lot of different combinations with the installer and pre-partitioning the drives, but I don't recall if I tried putting the /boot and /boot/efi on the same partition outside of the RAID. That may work, but I am not going back to try that combination now. 3. When grub (legacy or grub2) boots off of a RAID1 drive, it doesn't "really" boot off of the RAID. I just finds one of the pair, and boots off of that "half" of the RAID. It doesn't understand that this is a RAID drive, but the disk structure for RAID1 is such that it just looks like a regular drive to GRUB. Basically, it always boots off of sda1. If sda fails, you have to physically (or in BIOS) swap sda and sdb in order for grub to find the RAID

[CentOS] CentOS 7 install software Raid on large drives error
Greetings - I am trying to install CentOS 7 into a new Dell Precision 3610. I have two 3 TB drives that I want to setup in software RAID1. I followed the guide here for my install as it looked fairly detailed and complete (http://www.ictdude.com/howto/install-centos-7-software-raid-lvm/). I only changed the size of the partitions from what is described, but ended up with the disk configuration error that won't allow the installation to complete. The error is: You have not created a bootloader stage 1 target device. You have not created a bootable partition. So I am clearly missing a step in setting up the drives; likely before running the installer. My disks are blank raw disks right now with nothing on them. Reading the RHEL Storage Admin Guide (Sec. 18.6, Raid Support in the Installer) this should be supported, but I am assuming I may need to do something different because the drives are greater than 2 TB. I have a SystemRescueCD that I can use GParted to do some setup in advance of the installer, but am not sure of what exactly I need to do. My objective is to RAID1 the two drives, use LVM on top of the RAID, install CentOS7 as a KVM host system, with two KVM guests (Linux Mint and Windows 7). Can anyone tell me the steps I am missing, or point me to a better tutorial than what I have found in my extensive Google searches. Thanks.

That way I understand which detail I need to look at, and what order all the details go together in.

In this case, even generic (non-RH or non-CentOS specific) command documentation is likely what you want.

[CentOS] Advice on CentOS 7, software raid 1, lvm, 3 TB disks
Greetings - I am preparing to order a new desktop system for work. In general the new system will be a Dell Precision T3610 with two 3 TB drives. I plan on installing CentOS 7 as a KVM host, with virtual machines for Win 7 Pro and Linux Mint. I am looking for some advice or a good how-to on configuring software raid on the two drives, then using LVM for the host and virtual machines. I have configured our company server (Dell T610) with hardware raid and LVM for a CentOS 6 KVM host and several virtual machines so I am not a complete novice, but have never setup a Linux software raid system, and have not played with a CentOS 7 install yet. I have been searching the web and forums for information and am not finding much for good guidance. Lots of gotcha's are popping up identifying issues related to CentOS 7, software raid 1, grub install, > 2 TB disks (or any combination of these factors). The CentOS Wiki has a good description of installing CentOS 5 with raid 1, but there is a big warning about being an unsupported (risky) approach. Can anyone point me to a good how-to, or provide some general guidance. Thanks.

[CentOS] Mirroring Disk (Apologies for the new thread I deleted the original)
Answers to questions... It really depends on your use case. I'm looking to be able to pull out old dead drive, and replace it with new (almost up to date) drive and reboot. The USB disk is a 1TB disk in a case. > Been considering dump and restoring to the usb disk periodically? or > maybe something using LVM or maybe creating and breaking a RAID 1 > array? Constantly making and breaking a RAID1 with a USB drive is probably not helpful. It's just more wear and tear on the OS drive, because it has to be constantly read in order to mirror the target drive, and your USB drive is probably not what you want to boot off of if your system drive fails. You'd be much better off with a permanent RAID1, but if you can't do that then at least make a RAID1 to a USB enclosure which contains the same size and interface drive as your current system disk. This way if it fails you can swap in the backup drive and not have to boot from a USB drive. Yeah I thought that would be the case, as I said above I'd like to be able to boot from the USB enclosure but the plan is to replace the failed internal with the disk from the USB enclosure. Would LVM be any help or is it just a complication? I defiantly leaning to the nightly dump/restore into a similarly formatted disk. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Raid on centos

It's got 4 bays for be used for data that I'm considering setup up woth softwere raid (mdadm) I've 2 x 2TB 2 x 2.5 TB and 2 x 1TB, I'm leaning towards usig the 4 2.x TB is a raid 5 array to get 6TB. Now the data is on the 2.5TB disks currently. So the plan so far. Building the array as a degraded raid 5 with the 2 x 2TB disks that are emply. Copy the data from one of the 2.5TB disks on to array. Add now empty 2.5TB disk to the Array and wait for it to rebuild. Copy contents of remaining 2.5TB disk 2 array. Add now empty 2.5TB disk to the Array and wait for it to rebuild. So questions... Is the above a stupid idea? Do I need to get involved in gptids? on disks this size? What format should I create the file system as? Should I get lvm involved somewhere?

Good morning, I've got a new system with a fresh 6.4 installation. I didn't check if the sound worked at first but I know it doesn't now. :) The system board is an ASRock Extreme6. The Specs say it has a Realtek ALC1150 audio chipset and 7.1 channels. I'm running KDE and an Nvidia X driver (I need the video performance of this driver - sorry about that). The System Tools for Audio Output list 4 devices: HDA Intel (HDA Generic) Default PulseAudio HDA NVidia (HDMI 0) The speakers are connected via the typical audio jack and when I test "HDA Intel (HDA General)" it says that the default device did not work and it is using the PulseAudio device. I tested all 4 devices and nothing ever played. I've also made sure I have the audio jack plugged into the right port on the board :) I Googled a bit and one site suggested reinstalling the alsa kernel module, which I did.

Host system is Centos 6.2 on a Dell PE T610 with hardware raid on a PERC H700. Raid 5 is setup across three disks with a fourth hot spare. I have created a volume group within the raid 5 encompassing most of my drive space. Within the VG I have created numerous logical volumes that are assigned to specific systems. Volume Group: vg_mei Logical Volumes: lv_earthroot lv_earthswap lv_earthvar lv_sequoiaroot lv_sequoiaswap lv_sequoiavar lv_sequoiahome lv_sequoiaecosystem Earth is my host system and Sequoia is one of the guest systems. lv_sequoiaecosystem is the space dedicated to our Samba server and is the LV that I was expanding to make more space available to the rest of the staff. I had successfully extended lv_sequoiaecosystem using the following command from root on earth (lvextend -L+50G /dev/vg_mei/lv_sequoiaecosystem). Issuing the command (lvdisplay /dev/vg_mei/lv_sequoiaecosystem) following this showed that the LV was successfully extended from 100 to 150 GB. I then logged onto sequoia as root and issued a df -h to determine which device needed the file system to be resized (/dev/vde1).

It is not on my Centos 6.2 system, and doing a little searching through repositories for that specifically, or e4fsprogs, and I can't find it anywhere to even try it. Any google reference seems to point back to resize2fs. I ended up booting a live SystemRescueCD and using GParted via the GUI. My notes indicate that is what I had done previously also. I am still stumped, everything that I have read indicates that resize2fs can do a live resizing on ext4 file systems. Can anybody confirm or deny this? Is the reason I can't do this because it is on an LVM logical volume? Thanks.

[CentOS] Resizing est4 filesystem while mounted
Greetings - I had a logical volume that was running out of space on a virtual machine. I successfully expanded the LV using lvextend, and lvdisplay shows that it has been expanded. Then I went to expand the filesystem to fill the new space (# resize2fs -p /dev/vde1) and I get the results that the filesystem is already xx blocks long, nothing to do. If I do a # df -h, I can see that the filesystem has not been extended. I could kick the users off the VM, reboot the VM using a GParted live CD and extend the filesystem that way, but I thought that it was possible to do this live and mounted? The RH docs say this is possible; the man page for resize2fs also says it is possible with ext4. What am I missing here? This is a Centos 6.2 VM with an ext4 filesystem. The logical volumes are setup on the host system which is also a Centos 6.2 system.

[CentOS] Installing CIFS on CentOS4
Hello, I have a CentOS4 install and I am trying to mount a Windows Server 2008 folder. When I use this command: mount -t cifs //10.1.1.17/Org/MR\ Ops/ test, it only mounts the Org folder. When I try the same thing on a newer computer (Fedora 15), it mounts all the way to MR Ops. So I am pretty sure that my cifs file needs to be updated, but I am having a really hard time doing this. I updated to the newest cif available for CentOS 4.9, but that still is not new enough. Can anyone tell me how to install the newer cifs on my CentOS 4?

Light from the monitor, reflecting off of you, will often trigger changes in the amount of light the ambient light sensor is seeing.

[CentOS] Slightly OT: First Time KVM and LVM on Centos
Greetings - I am a novice system administrator and will soon be purchasing a new server to replacing an aging file server for my company. I am considering setting up the new server as a KVM host with two guests; one guest as the Samba file server and a second guest as a testing area. My old server was set up about 7 years ago and has a 5 disk raid 5 configuration without LVM. I understand the benefits of using LVM and KVM in the right circumstances, but have never used either of them. I have spent a couple of days over the last week trying to understand how to setup a KVM host with guests, but there is an area that I still don't understand; that is the relationship between the underlying raid partitions, LVM, and allocating space to a host and guests. Many of the standard search term combinations in Google don't seem to be getting me anywhere. From what I have read so far I think that I want to have my file server guest using a raw partition rather than an image file, but I haven't found anything with examples or best-practices guidance for partitioning or volume management with hosts and guest VMs. So I am hoping that someone here can give me some pointers, or point me to some clear how-to's somewhere. Any help is appreciated. Thanks. Jeff Boyce Meridian Environmental www.meridianenv.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Here are the highlights and my comments to some of the suggestions that were provided, since I can't respond to every thread from the digest. The opinions both for and against OpenLDAP have made me take a little closer look at it, but my conclusion is that it is more cumbersome than what I really want to handle right now for the size of the network. I have looked closer at Samba/Wins/Winbind, etc. and it looks like the main source of my current problem is that my Samba network is setup now as a Workgroup and not as a Domain. I didn't understand that difference when I ran across the quote I included above. It looks like if I change to a Domain and configure it properly with Wins/Winbind that I should be able to have the single point password changing option occur from the Windows desktop. I am now re-reading sections of my copy of the Definitive Guide to Samba 3 which should help me (although it was published before Vista and 7, which all my workstations are now). Also thanks to some for the suggestions of using ClearOS or Webmin. I do have Webmin installed and use it for some of my administrative functions. So if I do try playing around with OpenLDAP I will certainly see if it will reduce my learning curve on getting it setup properly. With the new gateway box that I mentioned above, I have been planning on installing ClearOS on it, so I will take a look at how it might be used to learn about using LDAP. Although I was thinking to have this box function more strictly as a gateway than providing services to the internal lan.

[CentOS] User accounts management for small office
Greetings - This may be a little off-topic here so if someone wants to point me to a more appropriate mailing list I would appreciate it. I administer the network for my small company and am preparing to install a new server in the next month or so. It will be running CentOS 6 and function primarily as a Samba file server to 10 Windows workstations (XP, Vista, 7). It will also host our OpenVPN server and possibly our FTP server; however I am hoping to move our FTP server to a gateway box when the new server is installed. The issue that I would like to be able to resolve when the new server is installed, is that currently if a user wants to change the password on their Windows workstation, I have to manually update that new password on the Linux user account, and also manually change the Samba user account. Manually updating the password in three different locations is a minor headache that I would like to correct. I have been researching and reading lots of information about account management to try and understand what is available, and what would be the best fit for my network size. Much of what I have read is related to larger networks or larger user bases, which seem to have a lot of extraneous stuff that would be unnecessary in my small user environment. I looked into OpenLDAP, and have recently been reading about Samba/Winbind. But after encountering the following statement in the Samba documentation, I am still lost about what I could, or should, be using. "A standalone Samba server is an implementation that is not a member of a Windows NT4 domain, a Windows 200X Active Directory domain, or a Samba domain. By definition, this means that users and groups will be created and controlled locally, and the identity of a network user must match a local UNIX/Linux user login. The IDMAP facility is therefore of little to no interest, winbind will not be necessary, and the IDMAP facility will not be relevant or of interest." My only goal is to be able to allow my users to change their Windows password at their workstation and have it perpetuate through the system so that it also changes their Linux User and Samba User account passwords. I don't expect to ever have more than a dozen users, so I want something that fits our size network and is simple to administer. I am not looking for a how-to to set something up, but some opinions about what I should consider using, and why it would be a good fit to achieve my goal. I can do the additional research to understand configuration once I know what I should be researching. Thanks. Please cc me directly, as I only get the list in daily digest mode.

By default Thunderbird creates a local cache for IMAP accounts -- for large accounts, this can be problematic. Have you tried disabling the local synchronization?

Re: [CentOS] how do export a block device via eSATA?
I've started building a JBOD out of a Supermicro case for expanding the available storage on my home network. So I have a few comments about what I learned so far about using Supermicro as JBODs. Supermicro has several multi bay chassis as part of their current product line but I'm looking to do this on a budget so I took the ebay route. I found some reasonably priced 12 bay cases use "Supermicro 12 bay" as your search criteria. I found a good deal that cost a tad over two hundred bucks. I was a bit drawn to the Supermicro chassis since they make a power card that allows the front power button to control the power supply without a motherboard. It is designed with the intention of using the cases as JBODs. CSE-PTJBOD-CB1 The backplane port(s) can be mapped to the outside with something like this: http://www.pc-pitstop.com/sas_cables_adapters/ Since my case doesn't have an expander backplane and is instead comprised of 12 individual SATA ports In my case I'll end up with three ports exposed since each connector supports 4 drives. If you have an expander backplane it could be as simple as a single cable. >From there you'll connect the external SAS ports to a SATA/SAS adapter. It is possible to get SATA/SAS cards that already have externally available SFF-8088 ports or if they are all internal you can expose them externally by using the same SFF-8088 PCI brackets on the server side. I intend on hooking this JBOD up to a couple of computers which is why I am not just putting a motherboard and running it as a full on server. On a side not since this is for home usage a few things I plan on doing to make it better suited is replacing the hotswap 800 watt power supply with something high efficiency and at least half the watts and use quieter fans possibly putting them on some kind of speed control jeff On Mon, Feb 14, 2011 at 8:05 AM, Les Mikesell wrote: > On 2/14/11 7:57 AM, Ross Walker wrote: >> >>> I just had this idea of exploring eSATA since most machines already >>> have an eSATA port.

Eventually, you will have to move on. What are the motivations for the customizations? Do newer or alternate MTAs have added features that can replace those customizations? Postfix can be highly customized through configuration and is not that difficult to learn. As a migration path, I would separate the MTA (sendmail) and the imap server. Go with cyrus or dovecot on a new machine (virtual?) and use imapsync to move messages to the new box during a maintenance window. As stated in other responses, cyrus has it's own mail storage format with individual files for each message and dovecot supports several formats including maildir. It should not be difficult to have your existing sendmail deliver messages to the new imap store either directly or with a very simple postfix MTA on the imap box. Once mail storage is fixed, you can start working on de-customizing your MTA. And with regard to backup space, it might be time to suck it up and tell your users that you need to implement mail quotas. How much are you backing up from "Sent" and "Trash" because nobody maintains their mail folders? A quota can be a great tool for teaching basic mail folder housekeeping. -- Jeff ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] MacBook Pro and CentOS-5
This is off list topic, but I have seen weirdness in airport cards on macs especially when connecting to Apple's Airport. A cheap fix is to buy a 2nd wireless access point and make sure to use that in bridged mode so it is not acting as a router and wire that to your airport base station. I like said before trying using an external hard drive to install CentOS onto and try your wireless card and other hardware drivers.

Re: [CentOS] MacBook Pro and CentOS-5
Being a mac system admin and support specialist and CentOS guy. I can say you can always try using an external hard drive to boot the Mac off of and install CentOS on that drive to play around and test out all the drivers for video card, wireless, etc... I don't boot into CentOS but have it running in Parallels and it runs great. I also do recommend to get your Mac repaired too, just be sure to clone your hard drive off to an external drive before sending it into the shop. Apple is known to completely erase hard drives with no warning. -Jeff On Nov 15, 2010, at 8:44 AM, Les Mikesell wrote: > On 11/15/2010 10:18 AM, James B.

Afternoon, Sorry for being dense but I can seem to configure the repo for atrpms correctly.

Re: [CentOS] Kickstart from tagged VLAN?
I've still been keeping this one simmering back burner and trying to figure the workflow for getting a system up and running with minimal user interaction. I do realize the PXE agents don't have any concept of tagged vlans. The thought was more along the lines of having the ability to specify a tagged VLAN id at the boot prompt when running an install from the console using a CD or USB drive. (ie passing arguments to the boot loader "linux ks=http://localwebserver/ks/server.ks ip=10.10.10.10 netmask=255.255.255.0 gateway=10.10.10.1 dns=10.10.10.53) My previously supplied link had a link to this article about Anaconda being enhanced to support VLANs: http://rhn.redhat.com/errata/RHBA-2009-0164.html I've been experimenting with Spacewalk/Cobbler so this kind of extends beyond just a basic CentOS install but whether Cobbler is part of the equation or not, the crux of the question is to verify if Anaconda has direct support for VLANs. I've been out of the office since I originally posted the question so I haven't had a chance to setup some systems to verify it for myself yet. I was hoping this was something someone else had previous setup something like this and could verify whether it would work. I plan on taking some time to try this out later today. This is how I envision the workflow: a switch interface has three VLANs setup untagged 99 (Spacewalk/Cobbler/PXE/dhcp enabled subnet) tagged 100 (main server subnet) tagged 101 (backup network subnet) Once the machine boots up it will get an dhcp provided IP from VLAN99. Cobbler has added an PXE entry for that machine to tell it what kickstart file to grab which it downloads via HTTP. Once that has been downloaded and processed the kickstart file will have the two tagged interfaces (ie eth0.100 and eth0.101) specified and from this point forward it continues the rest of the install process through VLAN100 interface, eth0.100. After it finishes up it, the system reboots and then no longer needs or uses the untagged VLAN. One of the issues I'm trying to work around is I'm in an environment when I don't have end to end control over everything. In order to get an interface changed I have to rely on a different team to make the change so if I need an interface reconfigured from untagged to tagged or from VLAN abc to VLAN xyz, I have to wait on someone to do it for me. So the logic is to have everything in place that I need from start to finish. When it's all over then the temporary untagged interface can be removed from the switch interface without disrupting the configured and deployed system. Hope that all makes sense. jeff On Wed, Jul 7, 2010 at 5:11 PM, Blake Hudson wrote: > Original Message > Subject: Re: [CentOS] Kickstart from tagged VLAN? > From: Les Mikesell > To: CentOS mailing list > Date: Friday, July 02, 2010 7:33:45 AM >> Finnur Örn Guðmundsson wrote: >> >>> On Cisco switches it would be called "native vlan" if i remember correctly: >>> >>> One way of doing it (if using Cisco :): >>> >>> interface GigabitEthernet0/1 >>> description nodeX >>> switchport trunk native vlan 100 >>> switchport trunk allowed vlan 100,101 >>> switchport mode trunk >>> spanning-tree portfast trunk >>> spanning-tree bpdufilter enable >>> end >>> >>> >> Doing it that way would force you to change all of your switches and hosts >> that >> know about vlan 100 at once.

[CentOS] Kickstart from tagged VLAN?
I've searched around but haven't found a definitive answer yet, is it possible to kickstart from a tagged VLAN? I found this bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=431915 But I can't find out how far the vlan support goes. I haven't found anything about it in any kickstart docs. I have two tagged vlans: Vlan 100 - server subnet Vlan 101 - backup subnet >From start to finish anaconda needs to pick up a dynamic address from vlan >100. After that the kickstart file specifies the static adress from vlan100 >and it's address from the backup subnet. Anyone know if this is currently >possible?

[CentOS] Grub Error 22; no Windows
Hello, I have a GridEngine setup with 5 subnodes and two RAIDS attached. I backed up the OS drive - 120GB - to an external hard drive - 500GB - using ddrescue. The OS drive is partitioned as: sda1 has the OS and is about 7 GB sda2 has /var and is about 4 GB sda3 has swap and is about 1 GB After backing up, there were 4KB of errors, but all at the end of the disk around 118GB. This used to be a partition back in the day, but I deleted it accidentally. I want to back up to this new larger disk b/c the original 120GB disk is discontinued. I boot from a live cd - SystemRescue CD - and run e2fsck -c -c -C 0 y on sda1 and sda2 on the backup drive, and it seems to finish fine. Then I replaced the OS drive with the backup drive, and it goes to boot, then Grub Loading Stage 1.5; Error 22. Here's the important stuff from fstab: # This file is edited by fstab-sync - see 'man fstab-sync' for details LABEL=/1/ ext3defaults1 1 none/dev/ptsdevpts gid=5,mode=620 0 0 none/dev/shmtmpfs defaults0 0 /dev/md0/export ext3defaults0 0 none/proc procdefaults0 0 none/syssysfs defaults0 0 LABEL=/var /varext3defaults1 2 LABEL=SWAP-sda3 swapswapdefaults0 0 /dev/sdb1swapswapdefaults0 0 # The ram-backed filesystem for ganglia RRD graph databases. tmpfs /var/lib/ganglia/rrds tmpfs size=252709000,gid=nobody,uid=nobody,defaults 1 0 /dev/hda/media/cdromauto pamconsole,exec,noauto,managed 0 0 I boot up from the live cd, and then tell it to search for bootloaders on the drives, and it finds one, and it goes through, and then throws errors b/c it is mounting the OS /sda1 drive and then trying to run fsck on it. I tried setting the error-check values to 0 for /1 and /var, but it is still trying to error check it. My blkid says that sda1, sda2, and sda3 all have different UUIDs. sdc1, sdd1, and md0 all have the same UUID. md0 is a RAID1 comprised of sdc1 and sdd1. sdc and sdd are identical drives. This used to happen, and I would just restart a couple of times, and it would sneak on past the error eventually, but to no avail this time. Does anyone have any ideas? Thank you so much!
