we have 3 identical IBM x3550 M2 with identical OS installation. All 3 have 32GB RAM and run Centos 5.5 with Kernel Version 2.6.18-028stab070.14 (virtuouzzo). We now wanted to upgrade the RAM of all 3 Machines with another 32GB RAM.
Maschine 1 runs great with the 64GB RAM but the other 2 get extremly slow when we run them with 64GB RAM. After init it takes about 30 minutes till the OS is up (without errors). Then it takes another 5 minutes to get a shell over SSH. Working with this Maschines is awfully slow. With 32GB RAM everything is fine.
All RAM slots are full, so it is not possible to insert them the wrong way. We have no idea whats wrong with the other 2 x3550 or with CentOS and why 1 Maschine is running fine.
I have an old IBM Xseries 300 server that i can use. So, i am trying to install Centos 5.3, but during the installation , no disk can be found. I have 2 disks (1+1 in mirror) connected to an IBM serveraid PCI card.
I installed Debian Lenny, and it recognize the card (so the disks) immediatly.
I recently acquired a Dell Vostro 3550 (new model) and today I installed Ubuntu 10.10 (32 bits). I am not able to see the available wireless connections (although the bluetooth is working just fine)... Apparently it is also not recognizing its drivers, since on "Additional Drivers" I have no items.
I have loaded openSuSE 11.4 on an IBM x3400 box with an Adaptec ServeRAID 8k-l SAS harddisk adapter. openSuSE 11.1 was previously loaded on this box and was using XEN kernels.) The default "desktop" kernel boots and operates correctly. I use this machine to run other XEN virtual machines to run different versions or our companies printer controller application. When I attempt to boot the xen kernel, the kernel cannot locate the root partition (or any other partition) on the hard disk. Here are a few lines of kernel output:
Recently I upgrade to the latest Nvidia driver for Linux. I checked that it was compatible with my Ubuntu 10.04 x64 system and my geforce gt 220 graphics card. I decided to go with the newest beta ver 260.1904. Installation went well, better actually than other times I tried to install the newest driver from their site. After installation was finished I restarted and let my system load up. As soon as it got past the ubuntu logo, the screen just went blank as if there was no signal.
I determined that everything but the display was working. When I pressed ctrl-alt-F1 the numlock light turned off (this usually happens) and was still toggle-able. When I went through the other x-servers (ctrl-alt-(F2-F6)) the light went out but could be turned off and on by hitting numlock. When booting in from recovery mode, the screen displayed up to the point where it would show recovery options with no noticeable error showing before the screen turned off. This is what worries me the most.I don't think it is my Xorg.conf because I replaced with a backup and still have the same problem.Does anyone have any ideas about why this is happening or how I can at least see the terminal. As a side note, its definitely not the card because the card worked fine before, works in windows and live cds, and I tried with an older nvidia card and had the same problem.
Recently upgraded to Centos 5.5 and was suprised to see that the distro still is running php 5.1.6.Anyone know when Centos RH plans on upgrading php in future distros?
I have installed CentOS 5.3 on my PC which has an Atheros AR8121/8113/8114 Gigabit Ethernet. Unfortunately 5.3 has no drivers for this LAN Card. I searched the Google for drivers but was unable to find any. Does the 5.4 has them? If yes then how can i upgrade it to 5.4 without Network connectivity?
I have been using Centos on a VPS for about a year and love the speed and simplicity. So, I would like to convert my home computer to Centos 5.5 Currently, the computer is running Ubuntu 10.4 x64. The drive has 3 partitions (a main partition that I would want to format and install the Centos Base), a swap partition which can be formatted and used as is and a third partition that boots to /home.
I have a few concerns: 1-If I edit the third partition in the Centos install as "boot to /home," Will everything (theoretically) work? The only applications that concern me are E-Mail (evolution) and OpenOffice. I know that Centos 5.5 uses Evolution 2.1.x and Ubuntu uses 2.2.x but just shouldn't be too much of a problem. (I can copy the mail folders from a backup to the .evolution directory.)
2-My /home partition uses ext4. Is using this on Centos 5.5 "looking for trouble"?
Having all kinds of trouble with my video drivers after upgrading to 10.04 The error message I get is
Unable to initialize PCS database Missing PCS default file .etc/ati/amdpcsdb.default No devices I keep reinstalling my video drivers from the ati-driver.run file for my radeon 2400 card - seemingly successfully - but it doesn't seem to help and when I reboot i just get the limited video function
Is i possible to upgrade from a point release, like 5.3, to another point release, like 5.4, using yum ? Or, even if it is possible, is it better to just do an install of 5.4 and choose the upgrade option on top of my 5.3 installation ?
I recently upgraded from centos 5.2 to 5.3 ( using yum) two desktop computers with a similar configuration (different hardware but similar software configuration). In both cases I saw that yum-updatesd has stopped working. The daemon start at boot and remain silent for a while (an hour or more, without signaling the presence of any update package) then suddenly the process dies without any messages in the log. Using lsof i saw that the daemon open a lot of file and library, but it newer try to connect to any repository.Now i have just launched it in foreground and debug mode (yum-updatesd -f -d) and i'm waiting for some useful debug messages.. Has someone had a similar experience ? What else can i try ?
want to upgrade php from 5.2 to 5.3 it can be possible with RPM and YUM but i want to know step by step how it can be upgraded using tar.gz file of PHP and from where i can download it.
I have installed Centos 5.6 (32 bit) in a virtual machine and would like to know if it is possible to update it to a 64 bit installation (probably I will also need to move to another version of the vm player too) or if there is any kind of compatibility lib(s)
I'm running MySQL 5.0 on a production server and I require to upgrade mysql to version 5.5 to get a new collation support. What is the best procedure to follow? I cannot find MySQL 5.5 on the standard repositories. A yum install would be the safest, correct?
I had a 5.3 CentOS server running beautifully. I upgraded to 5.4 for the improved power managment on my hardware, as well as improved network drivers. Unfotunately upgrading from 5.3 to 5.4 completely breaks vmware server 2.0.2.[URL]..
Unfotunately the downgrade of glibc is still resulting in unstable performance. Is it possible for me to downgrade to cent os 5.3 without re-installing the operating system? I'm really stuck here,
After upgrading to 5.6 I was trying things out and noticed for some reason the php on my server has stopped working. Anybody have a clue what's wrong ? I did read the release and it did mention the upgrade would then change my php.
I need to upgrade one of our systems from its current distribution, Fedora Core 7, to the most recent version distribution, release 5.4, of the CentOS operating system. Can I do an in-place upgrade of the operating system without any adverse side-effects? Are there any issues that I should be concerned with before proceeding?
When using YUM UPDATE from the prompt more than 230 items are scheduled for update however when the download process has completed I receive errors regarding Perl dependences such as:
file /usr/lib/perl5/5.8.8/List/Util.pm from install of perl-5.8.8-27.el5.x86_64 conflicts with file from package perl-5.8.8-18.el5_3.1.i386
I am unsure how to overcome this. It occurs on two different servers.
I issued "yum update" and the process ended with a transaction check error(see below). Running rpm_check_debug Running Transaction Test Finished Transaction Test

I installed Oracle Database on this server few months ago. I see in /etc/yum.repos.d directory a public-yum-el5.repo file with entries pointing to Oracle which must have come from that installation. Now how do I proceed from here?
Due to all the "fun" I had upgrading spamassassin from 3.2.5 to 3.3.1 on C55 I thought I would detail it here so as to possibly save others from all the frustration I have endured. There are probably a zillion different ways to make this work but this is how I did it and it seems to work well.
1) Acquire spamassassin rpm. I downloaded several different versions from various sites and had problems with all of them so I ended up grabbing the SRPM from Fedora 13 spamassassin-3.3.1-2.fc13.src.rpm. This of course will not load onto C55 as rpmbuild has changed so I loaded it onto a FC13 box and then TARed the SPEC & SOURCES directories, copied them onto a C55 and built SRPM from there.
2) Install on C55 The new spamassassin requires several updated packages to make it happy. a) perl-Mail-DKIM greater than 0.31. I cheated and used this one from FC8 perl-Mail-DKIM-0.32-3.fc8.noarch.rpm b) perl-socket6 that is 2.0 or later. I got this one from DAG perl-Socket6-0.20-1.rf.x86_64.rpm c) perl-NetAddr-IP that is 4.0 or later. Again DAG saved the day perl-NetAddr-IP-4.007-1.rf.x86_64.rpm d) the spamassassin of course :) Actually I built them from the SRPMs as I needed both the 32 and 64 bit packages for various servers.
3) Run sa-update --D to get the latest rules then restart the spamassassin service. For those who do not have access to a FC13 box you can get a copy of the SRPM I made here [URL].
I installed PHP 5.3 from remi repository and now some PHP pages end up as blank pages. Joomla pages load with no problem but iDevAffiliate pages end up as blank pages. Could it be something in the php.ini file? I have no idea where to look. Any ideas?
I find my self abit stuck upgrading OpenSSL to the latest version. The situation is that i've been running LAMP servers just fine by installing the web services from the repositories AND the web services from source. However im now in the process of making a PCI-DSS compliant server LAMP server. I've just had the vulnerability scan report back and its failed due to the OpenSSL having vulnerabilities and it tells me I must upgraded to version higher 1.0.0d.
I've basically spent hours and hours trying to get this working along with research but I dont seem to be having much luck with this one
Im using a fresh install of CentOS and trying to create a RPM using the source code and rpmbuild, I read this was the best way I read, and this is my first time using rpmbuild.
Code: yum -y install rpm-build make gcc gcc-c++ perl mlocate cd /usr/src/ wget http://www.openssl.org/source/openssl-1.0.0d.tar.gz updatedb tar -zxf openssl-1.0.0d.tar.gz openssl.spec
I have 2.6.18-164.2.1.e15 running on Hyper-v. I did yum update and noticed that kernel is upgraded to 2.6.18-164.9.1.e15. If I try to boot into the new kernel it hangs with message first "switchroot mount failed" and then "kernel panic". This is probably related to Hyper-v drivers installed in the old kernel. First question: Do you think this is correct? Is it possible to somehow disable Hyper-v drivers so I can boot into the new kernel and then reinstall drivers? There is nothing in Microsoft documentation about uninstalling Linux Integration Components.
I have a CentOS 5 based Linux system with a 3Ware 9550SU RAID card and four 500GB drives set up in a RAID5 array (3 in the array and 1 hot spare).
I want to 'replace' these drives with four 2TB drives without data loss. My server case has a total of 8 drive bays all hot-swap and all attached to the RAID card, this means I have four empty drive bays on the RAID card.
One thought is to put the four new 2TB drives in the empty drive bays, configure them in a new RAID5 array. Then the question is now to I "mirror" the original RAID5 array over to the new one?
This is just a thought though, I am not sure it will work. In short my question to this forum is how do I accomplish this upgrade?.
I am trying to create a workflow for upgrading various systems using kickstart. I was hoping folks can point me in the right direction.I have a system which already has Centos installed on it. However it is a stripped down version of Centos using a custom kickstart installer. Now I would like to upgrade these systems, using an updated kickstart file spec. I would like to be able to copy over required files into a partition on the system, make a change in the grub.conf, reboot the system and expect the system to use the kickstart file and the iso file located on a partition on the system to self upgrade the entire system.The partition which holds the iso on these systems may be raided, or it may be an LVM partition.
How do I specify in the kickstart file that the location of the iso is on an LVM partition? Is this even supported? I have tried specifiying the disk like so:
< -- isolinux/ks/harddrive.cfg -- > upgrade text harddrive --partition=mapper/VolGroup00-LogVol02 --dir=/isolinux
[code]...
But the installer did not seem to like it. Instead of the iso, can I put the entire tree instead? Would that work?
