[CentOS] Centos installation Vs Disk partitioning
Dear all, I'm trying to setup a development server which hosts a number of virtual hosts.and i need your advice with the following: 1. What's the best Filesystem to be used with an apache server?Relevant info: i. Mysql DB size' 1 GBii. Code directory size' 8 GB (Max file size is 5 KB)2. What's the best file structure to maximize seek time from drives?Relevant info:i. 2 X 1 TB SATAII 64MB blk Edition Int HDDii. 1 X 320GB General info: I have an additional directory which hosts all my code under /Development . this directory has a size of almost 300 GB.14 Virtual Hosts would be created on the server under /etc/httpd/VHosts/ I was thinking of the following structure: Drive A (320 GB): OS Drive B (1 TB): Mysql + /homeDrive C (1 TB): /development + /opt Would this work? i followed no guidelines with the above setup, it's just using my own logic. so i'd appreciate an expert advice with this. Thanks, --Roland ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

My immediate hunch is ... and I'm sorry to say it ... but your NIC is often referred to as Realcrap NICs - unfortunately that's not without a reason. However, check what lspci says. If you don't see your NIC there, it is most likely a hardware issue (or caused by BIOS changes).

You may also try to reload your NICs kernel module (modprobe -r && modprobe ). Another thing is to figure out what you did before it stopped working. If you want to say "I did nothing" and that means you rebooted your box, upgraded packages or other things which might sound safe and innocent, it might just as well be connected. The only times I've experienced issues and where I really did nothing, it was related to physical hardware issues. But those times where I did "nothing" (rebooting, upgrading, innocent configuration changes) and got troubles ... it was always connected to that I did the "nothing" thing. Sometimes even disabling "useless features" in BIOS turned out to disable quite a useful feature after all. So no rock is too small to be turned around now. Go carefully through all your changes you did before it stopped working. kind regards, David Sommerseth ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thank you for the discrimination, but it's not appreciated. This is not a multi-million dollar enterprise cluster, so please don't see it as such. It's an in-house development server and really doesn't justify thousands of dollars' worth of hardware. The NIC was working fine for about 2 years now without a hiccup, out of the box when we first installed CentOS. Something went wrong, I just don't know how to actually fix it without re-installing CentOS :) > > However, check what lspci says.

The kernel & CentOS itself was upgraded last year sometime, when CentOS 5.5. was released and it was running fine since then. I really did nothing. We were working on a client's stuff, in fact, accessing data over SMB from the server. Would that have caused an issue? The network just dropped and hooked a KVM onto it to see what's up. eth0 was still using IP 192.168.1.250 (configured when we installed it) I then restarted the network scripts (/etc/init.d/network restart) and eth0 didn't come back up. So, it could either be a faulty network (yes, expensive card can also fail) or the driver doesn't load properly anymore. BUT, I don't know where to start fixing the problem. > > The only times I've experienced issues and where I really did nothing, > it was related to physical hardware issues.

So are you saying a spook accessed the BIOS of a machine which was running for about 3 years, without any hardware changes? I don't, ever, change BIOS settings once a machine is setup. Why should I? Besides, the machine doesn't have a monitor or keyboard and I need to take the one off my desk, walk over to the server room plug it in and then access it that way. I don't know about you, but I don't do this randomly every day, it's a waste of time. > > So no rock is too small to be turned around now.

Re: [CentOS] how to recreate eth0 - Realtek 8169sc
I love realtek - the resources they use tend not to conflict with other cards or hardware, they don't use much cpu time, the drivers are mature, and they don't cost much. What could be better? There does seem to be at least one onboard realtek chipset that can have driver issues, but I use the 8169 without problems. But hardware does fail. And any brand of nic can fail in odd ways. I'm guessing you've swapped it out? Bios settings can change if the on-board battery is dead and the system loses power. (It can set to defaults) But bios settings rarely affect nics - you're more likely to see boot problems from a change in drive boot sequence. I don't suppose you have a vpn on your lan? I noticed you use the 192.168.1.x address range, which is one of the most common ranges in the world. If someone connects to your vpn from home or workplace, and if they use the same range, and if theres a bridge, addresses are going to conflict. If you delete your ifcfg-eth0 or ifcfg-eth1 files, centos will recreate them if it sees the nics at boot. But it tends to enable eth0 and disable eth1 or higher. You should have backups of your originals for that reason... I bet you wish you had a tcp/ip based kvm switch system about now... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

This is purely cause the ADSL router in the office is on the 192.168.1.0 subnet, so it's less hassle when it needs to be swapped out to get it back up again.

On my network I am using a combination of rsync and DRBD volumes to make copies of my data. The main large drive is rsynced regularly to another system. The daily changes (mostly documentation) is mirrored on two drives on one server and that volume is DRBD'ed to the other system.

I like your analogy David..." rock is too small to be turned around now" I think you put it in the right context.

If it works from any one of these LiveCDs than the network card works and it could be a configuration issue in your installed CentOS. If it doesn't work on any of these LiveCDs that are all using different drivers, then it might be the card. Also .. since this should be easy to do, switch network cables (in place, keeping their existing switch ports) with another system that is running fine. If the other system starts exhibiting strange issues and this system magically starts working fine, it could be a cable or switch configuration issue. Although most people don't have these sitting around, you could connect a USB nic to the machine and see if the problem occurs with the installed CentOS but using a different NIC without cracking the case.

Re: [CentOS] how to recreate eth0 - Realtek 8169sc [SOLVED]
Rudi, Sounds like a module conflict/misconfiguration, but anyway glad its working back. have you upgrade this system with the latest kernel build. I am guessing both onboard NICs are the same brand, take a look at messages and see if the card give me problems in the future. make sure you look for packet drops or errors that may hinder a bad NIC in the near future. Put your admin hat on a design a good plan to tackle this issue so you don't sweet it in the near future.

Re: [CentOS] how to recreate eth0 - Realtek 8169sc [SOLVED]
Hey, If it happens again, or maybe it might show in /var/log/messages, if there was a MAC address conflict in the ifcfg files.

Re: [CentOS] how to recreate eth0 - Realtek 8169sc [SOLVED]
Tommy, I think your scenario only pertain to those of us that clone macs with different prefixes, we are assuming that rudi is using the original MAC from the actual device. Not two macs are equal unless you change the physical device parameters via mac-changer/modification. Let's hope he is not aliasing the original mac with a multi-fake mac group link to the original NIC. >>> Tommy E Craddock Jr 1/10/2011 8:54 AM >>> Hey, If it happens again, or maybe it might show in /var/log/messages, if there was a MAC address conflict in the ifcfg files.

You should re-install the O/S. You can re-use the existing volumes, but you should have the installer remake (as in mkfs.ext2/3) the root (/), /var, and /usr file systems. You can keep /home, etc. as is (assuming it is a separate file systems. If you have enough space available in your volumn group, you can create a new root file system for the 64-bit system and use that. You can re-use the /boot file system if you plan on making things 'dual boot'. You can do this (except create new logical volumns, unless you are using the GUI installer)) from the 'custom layout' screen in the installer. > > Thanks, > > Kai > > > ___ > CentOS mailing list > CentOS@centos.org > http://lists.centos.org/mailman/listinfo/centos > > > -- Robert Heller -- 978-544-6933 / hel...@deepsoft.com Deepwoods Software-- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If you don't already know that you need something special, use the default. The only potential issue would be if you have a lot of small files in one directory, or an extremely large disk. A daily rsync is not enough for protection against disk failures, and disks are exceedingly cheap. Your estimated disk usage is 9GB, and you have 2x 1TB drives. There's no excuse for not making that into a RAID. The Linux caching subsystems will handle most of the performance concerns you might have, as it will automatically cache things you use often. Don't think too much about one thing that has little benefit, while neglecting other things that do. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

As far as I can see you did not intend for me to make any alterations to it to begin with. With this file in place and ~/.Xresources renamed to ~/Xresources.test I started xterm from a gnome terminal. There were several changes in behaviour, so I infer that the file is recognized and loaded by xterm. However, the font size remains unchanged. I suspect that there is something wrong with the xfont configuation on this system since xfontsel can only see four fonts and there are literally dozens available. Since xterm apparently only knows about four fonts then it cannot be altered to use any other.

Re: [CentOS] replace x86 with x64 system and reuse existing LVM
Answering here to all three replies, and thanks for all of them! I think it should have been clear from my wording that I want to install from scratch and wipe the existing OS. I do not want to dualboot or "save" anything (or much) from the existing OS. I just want to reuse the existing LVM structure with all the existing guests and wasn't sure if this would be easily provided by the install wizard or if I needed to do something special. Or if I should just install via kickstart reusing the original kickstart file with slightly altered options (e.g. don't create volumes, just format the correct ones - which might be a tricky and easily mistaken one). So, as I understand, a normal install with the custom disk layout option should be able to reuse the LVM as I want it, right? Thanks.

It really does seem to come down to the fact that xfs is not finding the fonts and that therefore only the default fonts are left available to XTerm. I have tried configuring the FontPath argument in xorg.conf but all that manages to do is to stop the xserver from starting at all. I looked into the rc script and to me it is a nightmare. To begin with, instead of just configuring the font directories the startup script runs a font locater utility /usr/sbin/chkfontpath.

The system startup script for xfs makes reference to a /tmp/.font-unix directory. An error message appears on the boot details screen to the effect that lstat reports /tmp/.font-unix does not exist but I can find no reference to this error in any of the logs. After startup I can find that directory but it is empty. I have no idea how this is supposed to work but I suspect that the dynamic discovery and addition of the font directories is failing for some reason. -- *** E-Mail is NOT a SECURE channel *** James B.

Most packages don't actualy do anything where process-specific optimizations would make any noticable differences. Note: glibc itself is optimized for i686 and since just about all programs use glibc, they would all get this advantage. Optimizing the kernel not only relates to generic speed, etc. advantages but also a pile of kernel-level 'features' the newer procossors provide (stuff involving process scheduling, virtual memory management, and I/O / DMA addressing / processing). These various kernel-level 'features' are not accessable by user-mode processes, so adding in those features / instructions is not meaningful for user-mode code (most packages). > > For example in CentOS-5: > > kernel-2.6.18-194.el5.i686.rpm > php-5.1.6-27.el5.i386.rpm > httpd-2.2.3-43.el5.centos.i386.rpm > mysql-server-5.0.77-4.el5_4.2.i386.rpm > > Regards, > > -- > Santi Saez > http://woop.es > ___ > CentOS mailing list > CentOS@centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- 978-544-6933 / hel...@deepsoft.com Deepwoods Software-- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] RAID configuration suggestion???
we have several DELL R900 with PERC 6/E adapter in it. R900 using Redhat Linux. Each R900 have two PERC 6/E adapter and at least two MD1000 connect to it. Configuration 1: PERC 6/E -- two MD1000 PERC 6/E -- empty Configuration 2: PERC 6/E -- MD1000 PERC 6/E -- MD1000 Normally first MD1000 for database and second MD1000 for nightly backup. My co-worker told me there is NO difference on performance or battery life on botn configurations. I would like listen to your opinion on follwoing: 1. which configuration have better performance? 2. put two MD1000 on same PERC 6/E adapter will cause battery life shorter? 3. other comment? Thanks. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
