[CentOS-docs] Fwd: Typo in the FAQ at http://wiki.centos.org/FAQ/CentOS6, /etc/sysconfig/nertwork-scripts/ifcfg-eth0 should be /etc/sysconfig/network-scripts/ifcfg-eth0
Original Message Subject: Typo in the FAQ at http://wiki.centos.org/FAQ/CentOS6, /etc/sysconfig/nertwork-scripts/ifcfg-eth0 should be /etc/sysconfig/network-scripts/ifcfg-eth0 Date: Thu, 19 Jan 2012 15:31:08 +0100 From: Maximilian Heise maximilian.he...@gmx.net To: webmas...@centos.org Hello, I think there is a typo in the faq at http://wiki.centos.org/FAQ/CentOS6 Under 2. Why does my Ethernet not work unless I log in and explicitly enable it? There is a sentence If you are not using NetworkManager the same result can be obtained by editing the configuration file for the network interface ( normally /etc/sysconfig/nertwork-scripts/ifcfg-eth0 ) and toggling ONBOOT=no to ONBOOT=yes. The filename given there /etc/sysconfig/nertwork-scripts/ifcfg-eth0 is wrong, it should be /etc/sysconfig/network-scripts/ifcfg-eth0 or /etc/sysconfig/nerdwork-scripts/ifcfg-eth0, if you feel poetic ;) BR Max. ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs
[CentOS-docs] proposed 'howto'?
I'm horribly new at this. I just went through the process of setting up CentOS to use PAM + Kerboros for authenticating users to an Active Directory domain. I ended up having to read a lot of out of date or related howtos to get what I need. I documented the process I used and just got done re-doing it on a fresh VM install to make sure I covered everything. I figured rather than keeping this documentation 'in house' I'd see if there is a need/place for this on the Wiki. I'd be happy to give it a shot, or pass it along for someone else to post. ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

[CentOS] Wrong PV UUID
Dear All, I have one VG with one LV inside consist of four disk (and four PV) somehow the UUID is changed. I try to restore with the last known good configuration and use pvcreate --uuid xxx --restorefile xxx but I think when I first time do it I did use wrong UUID for two device. but haven't only using command above and haven't used vgcfgrestore. After carefully read the configuration, using hdparm to know device serial number I think I have assign the right UUID for each device. I succesfully use vgcfgrestore, but I cannot mount the device (unknown filesystem, bad superblock, etc). My questions are, is my first attempt to assigning (wrong) UUID make all the LVM corrupt? I see that all LE and PE is still there, the VG and LV size is right but still I cannot mount the volume. Is this just a bad filesystem or the data really gone? Thank you.

Re: [CentOS] No sound over HDMI using nvidia graphics card
Try changing the above to:
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 /dev/null 21 || : ;
}; /sbin/modprobe -r --ignore-remove snd-hda-intel
Save and reboot.
I tried that yesterday and it did not work, but I found out that this
happened for an entirely different reason. Tested again today and it
works. Thanks, Ned!

[CentOS] Redundant DHCP server with mixed static nonstatic ips
Hi, it's time to start our redundant dhcp server setup and I found some suggestions and tutorials. But all setups I found use either static or nonstatic ip adress management. For the static setup I'd setup two servers and copy the configfile from the 'master' to the secondary server and do a dhcpd restart. For the nonstatic I have to setup pool and failover peer configurations to have the lease information synced. My question: Can I mix both types of configuration? May be somewone has an example config for me? We use centos 6.2 and it would be dhcp 4.1.1. Thanks for any suggestion and best regards .

Re: [CentOS] Connecting ethX devices directly to a KVM/QEMU guest OS (no bridging)
On 01/19/2012 09:00 AM, Tait Clarridge wrote: I've Googled until I'm blue in the face, but haven't found a clear explanation of how I can assign each ethX device directly to the guest OS rather than going thru the usual bridge configuration. I need to allow the m0n0wall OS to assign the LAN and WAN IP addresses, if that's possible without using a bridge. I would think that it is a little easier to setup a bridge but not assign an IP address for it on the CentOS host. eg. /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=none ONBOOT=yes NM_CONTROLLED=no /etc/sysconfig/network-scripts/ifcfg-ethX (where X is the interface number of one of your intel ports and the HWADDR is the MAC address) DEVICE=ethX ONBOOT=yes BRIDGE=br0 HWADDR=xx:xx:xx:xx:xx:xx NM_CONTROLLED=no Restart the network service, then run brctl show - the new bridges should show up. Create the 8 bridges that you need and go from there, you should be able to assign them in Virtual Machine Manager to the VMs. Then in your VM guests you should be able to assign the IPs that you want. Thanks for your reply, Tait. I came to much the same conclusion after I eventually found an article about tinkering with the host kernel device tables to remap each NIC instance. I was going to try it until I discovered that the new motherboard I'm using doesn't properly support IOMMU in the BIOS, which the mapping trick requires. So much for that idea. Your method of not configuring a bridge IP address gets around having the NIC appear to my ISP as having some sort of rogue IP (even if I assign something in the 172.16... range). I wasn't aware that I could bring up the bridge without an IP. But a new problem arises ... one of the m0n0wall instances needs to use DHCP to get a dynamic IP from my ISP (the others are static, so they're ok). How do I get the bridge to proxy the DHCP request and forward the response to the VM guest? I brought up a test instance of m0n0wall but when it asks for an IP on its WAN side, the result is 0.0.0.0/8 so it would appear the request never makes it to the ISP. As a sanity check, I configured the WAN-side bridge to use DHCP and that worked, but it's the m0n0wall VM guest that needs to make the request, not the CentOS host. Suggestions anyone? In the mean time, I'll keep looking for a solution. Thanks, Chuck ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I brought up a test instance of m0n0wall but when it asks for an IP on its WAN side, the result is 0.0.0.0/8 so it would appear the request never makes it to the ISP. As a sanity check, I configured the WAN-side bridge to use DHCP and that worked, but it's the m0n0wall VM guest that needs to make the request, not the CentOS host. Suggestions anyone? In the mean time, I'll keep looking for a solution. Thanks, Chuck Hmmm. Is the bridge up and you can see the interface attached to it from running brctl show and ifconfig? Could you attach that output? If yes, then I would do a packet capture on the CentOS host on the eth interface attached to the bridge to see if the request makes it out. I'm running XEN at home and I have a very similar setup where I pass a VLAN from my switch that a provider modem is connected to into a bridge and it gets DHCP no problem (as long as the bridge and dot1q subinterfaces show up in ifconfig). The bridge should automatically send all the traffic out regardless of protocol, I doubt ebtables would be actively blocking anything as well and same goes for the ISP locking down with MAC addresses. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It would make much more sense to have 1 partition on each physical disk be a member of the MD raid5, then put that md in the volgroup, rather than having 9 sets of raids, I can only imagine they did it the way they did due to limitations of that ancient linux kernel in RH Linux 7.x (early Kernel 2.4, I believe). but, a newer linux kernel should see those md volumes, and should be able to import the LVM VG on them, if you really want to keep it intact. While I absolutely agree that it's a mess, there was a reason to the madness I'm sure.I think originally they were thinking smaller volume sizes which are then raided in mirror mode, so when a drive fails, only a small slice of data would fail. This is all theoretical on my part. The interesting this is, there's a CentOS 5.7 (Final) system in the mix that's also setup the same exact way. The F7 is merely a mirror backup of the CentOS machine. (I realized it's not an RH7, but Fedora 7, running kernel 2.6.23.17-88.fc7.) Either way, I do think a rebuild is in order, if only to simplify the raid ... I think what I'm going to do is upgrade the mirror system first after rebuilding the raid, mirror the main system, then swap machines while I then address the main one, which is running CentOS. Once that's back up and running, swap them back because the CentOS system is actually the larger, more powerful one (8 cores versus 2 cores on the mirror system.) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

This particular system is actually a mirror of a production server, a CentOS 5.7 (Final), which is also configured the same exact way as far as the raid goes. The data is already on a different machine. The one I'm going to be working on is the backup to the main server. So, even if I don't create a backup, it won't be a total loss as I just have to mirror it from the main system again. However, that being said, I do plan on backing it up anyway, just to cover my ass. In a moment of stupidity, I could very easy reverse the rsync command and end up deleting everything from the main server instead of mirroring it. :) I don't remember what version of the ext filesystem was current during the RH7 days, but I would seriously consider dumping the raid and reloading in onto a newly formatted ext4 filesystem. Agreed, but I'm also considering redoing the raid. I still can't come up with a good reason why it was created the way it was. I'm sure they had their reasons at the time. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] doing a new install on top of existing software raid-1
Hi all! One of these days I'm going to upgrade my centos 5.7 box (which is currently configured with raid-1 on two drives) to 6.x. i've been given to believe that I should be able to do a fresh install on top of the existing raid setup, i.e., without having to re-create the raid array, but just use the existing setup. and somewhere in the last few days (in this list I think) someone posted that Anaconda should detect the existing raid array and allow you to re- use it for a new install. so just as an experiment, I booted up the 6.2 DVD (not live) and took it as far as where it sets up the partitioning. So, was I unduly surprised when it DID NOT detect the existing raid? well, a little. more in the category of NOT ENTIRELY PLEASED, actually. I'd appreciate it if someone who knows something about linux hardware raid, and its intersection with Anaconda, could drop a few clues in my direction. thanks in advance! -- Fred Smith -- fre...@fcshome.stoneham.ma.us - And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.

I tried to boot a 5.x system with several raid1 sets with a 6.0 live dvd and not only did it not detect/match up the mirrors, it renamed and broke them so they no longer worked on 5.x. I think there are major differences in the way the kernel handles things. I probably won't try to access existing arrays again unless someone else reports success, and even then I'll probably pull one of the drives of each set until I'm convinced it is safe to sync them back. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
