HOW TO: CentOS Issue .. Kernel Update - SAS Drive
Apr 17, 2008I installed CentOS 5 with SAS drive. But i forgot install kernel-PAE for more 4GB RAM. (i'm using 8GB RAM).
But now when i trying to install kernel-PAE or update kernel. I have issue with hda and fd0 ...
"WARNING: No module megasr found for kernel"
When i 'cat /var/log/messages' i got:
kernel: end_request: i/o error, dev fd0,sector 0
kernel: hda: packet command error: status=0x51 { DriveReady SeekComplete Error }
kernel: hda: packet command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
I tried to 'google' they to find the solution, but now i still not find out ...
I'll try to reload OS. After reload OS, if i dont have floppy disk, how can i update kernel with no error?
Centos + Kernel 2.6.9-34.0.2- How To Upgrade Kernel
Apr 29, 2007Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then.
Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread.
In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources.
In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS.
Apparently when they used yum it said 34.0.2 was the latest kernel.
What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.

Kernel Update
May 8, 2008I installed CentOS 5 on a server with 2 quad core CPU's and 4GB of RAM. After the installation is done and during boot I see a warning that says "Warning only 3GB will be used".
So, just to check, I installed CentOS 4.4 and it sees all 4GB of RAM.
Are there any memory limitations on the distro? or could it be that the desktop kernels made their way into the iso's from upstream?

The big deal is Kernel is the most important update file IMHO. Because last time at another server i tried to update kernel by same method. And it said it failed to find template for Kernel or something like that. As a result my server didn't boot up and i had to request KVM and load older kernel
I am not sure if it will give same error this time but is there anything else that i need to do after kernel is updated except rebooting?
i just run /scripts/upcp and it updated all of the programs except kernel-pae. Now it says

Any Update For Kernel
Sep 14, 2007My server ( Pentium4 3.80GHz with 2GB RAM ) have 2.6.9-55.ELsmp, is there any update?
View 4 Replies View RelatedCan't Update Kernel
Mar 15, 2007I'm trying to set up this server at Layeredtech without a control panel running CentOS 4.x with kernel 2.6.9-34.EL with PHP, MySQL, and lighttpd
I'm having problems with the current kernel (high IOwait, etc.) so I did a yum update kernel which installed 2.6.9-42.0.10.EL but whenever I reboot it doesn't go back up.
I don't know where to look for errors because when I type # reboot then I'm disconnected from shell and I see no errors whatsoever. Then I have to contact LT to do a manual reboot because I can't connect anymore.
I really need to update the kernel.
How Big Risk Do I Take If I Don't Update The Kernel?
May 2, 2008I'm a Windows guy and can little or nothing about Linux. How big risk do I take if I'm using a Linux VPS and never update/patch the kernel?
I'm using CentOS 5 and LxAdmin. I can update the control panel, but I can not update/patch the kernel since I have no knowledge how I do that.
I'm using a unmanaged plan, so no help there.
Some of my sites are running Wordpress, but I'm always using the lates WP installation. I not using any other plugins that WG2, Gallery2, and remove max width.
Nobody except me have access to the VPS, and I have no other FTP accounts or something like that on the VPS.
I have no other scripts or any kind of dynamic pages on my VPS.
What kind of risk do I have here?
I'm currently having plans to cancel my second VPS that's using Win2003, and only use Linux in the future. I can cut my monthly expensive with 50% that way, but do I take a big risk doing it that way?
Install 32 Bit Pae Kernel On Centos
Apr 3, 2009i have a 32bit centos running with 8 gigs, but only 7 is registering when i contacted support they told me
Your server does in fact have 8GB of physical memory however the reason it is not being recognized is due to the fact that you are using a 32 bit operating system. By default, the 8GB would be recognized if it were a 64 bit OS however on a 32 bit operating system, you must install and boot into the PAE kernel (physical address extension) for the 8GB to be recognized and utilized. The PAE kernel can be installed through yum when connected to your server as root over SSH. Once you have installed the kernel, you will need to reboot the server for these changes to take effect
i tried
yum pae install
yum pae kernel install
both didnt work can anyone give me a quick step by step guide on how to go about this.

CentOS 5, CPanel 11, Kernel Buggy
Nov 18, 2007(The box, 2 years now, never had issues before all you will read...)
I do have a box at the IP xxx.xxx.xxx.xxx, which on 15th Nov. was: AMD 4200+
with 300 GB hdd for OS, and CentOS 4.5 on it...
Because the system was facing few load problems of wrong installed applications, we decided to do a fresh OS reload to the latest OS version and
cPanel.
on 16th Nov, the box was up and running with CentOS 5, and cPanel 11.
the kernel is: 2.6.18-8.1.15.el5
After few hrs the box was done and IO restored all backups in it anbd all worked fine, I realized that I couldnt access cPanel, page was blank for
everything.
Also, most pages (except simple html) where showing internal error 500.
I did a reboot. probelm was fixed.
After few hrs, problem came up again...
I left ssh logged in to see whats wrong.
I found out that every few hrs, that issue was happening:
Message from syslogd@server at Sun Nov 16 11:47:21 2007 ...
server kernel: journal commit I/O error
Then, we had techs to check HDD for errors. they did fsck, and said disk has to be replaced (at this point, without wanting to offend anyone, I have to state that 90% of techs in datacenters, or at least at mine --won't name them, 99% you guess which DC it is...-- are just low paid students that don't know SIMPLE things...) so we told them to replace the HDD and do OS reload in new drive...
So, on 17th Nov. we had online a new HDD, 400 GB with CentOS 5 loaded in it, and cPanel 11...
After few hrs and all working and backups recovered, the issue came up again!
This time, with exactly same error, techs told us it may be RAM, so they replaced the RAM and we waited...
In 2,5 hrs, bang, it happens again, same error.
They say, it might be the sata cable...
we replace it...
AGAIN ERROR.
we ask them to loook at it seriously, and after lot pressure, to avoid case that mo/bo or controller is wrong, they do upgrade us in a BRAND NEW colocated box, which was this time: Intel Core 2 DUO, 6300, with brand new 500 GB HDD and new RAM.
We recover in the new box the backups.
Box is online today at 18th Nov...
and the issue comes up again!
Message from syslogd@server at Sun Nov 18 11:47:21 2007 ...
server kernel: journal commit I/O error
I ask them what the **** is going on now and why after having all hardware replaced with new, and all OS reinstalled clean on new drives and new devices, 3 times, why we have again the same error...
And their response: power cable was loose, we replaced power cable...
Guys, sorry, this is really DUMP... loose cable cannot give that error...
and the error... continues!
Also, at this point, I have to let you know, that when this error comes up, (Message from syslogd@server at Sun Nov 18 11:47:21 2007 ...
server kernel: journal commit I/O error) the filesystem becomes READ-ONLY and
nothing gets affected, if we do a cold reboot by reset button, it comes up
again and all work PERFECT, until the issue comes back again.....
I am desperate with that, let me know what I have to do!

CentOS 5 - Problem Installing OpenVZ Kernel
Jun 22, 2008Just to make things clear, i am not new at setting up VPS nodes, i have set up all of my servers with the HyperVM/OpenVZ setup and they work perfectly, but im having a problem with a new server.
Just received my new server, installed HyperVM-Slave, rebooted but the OpenVZ kernel was not installed for some reason, so i manually installed the OpenVZ Kernel using the RPM as yum seemed to install the wrong kernel.
I then installed the kernel using RPM and got this error at the end of installation:
grubby: unable to open /dev/hda: No such file or directory
grubby: unable to open /boot/boot.b: No such file or directory
grubby fatal error: unable to find a suitable template
I have never encountered this error with any of my other servers before...
Also after installation everything seems to be correct. /etc/grub.conf has the new OpenVZ kernel displayed, and default is set to 0, so upon startup it should be booting the correct kernel, but the thing is, when i reboot the machine the default kernel is loaded even though the grub.conf is configured to load the OpenVZ Kernel.
Im thinking that this may be due to the error i got when installing the kernel.
CentOS 5.3 Default Kernel RealTek Support
May 15, 2009I'm not sure if anyone else has come across this but I'm sure you are all aware that CentOS 5.3 default kernel comes with realtek support.
But the default realtek drivers have a bug in them when it slows down upload and downloads drastically and shows ping times above 2000+ ms in the same datacenter.
A fix for this is simply upgrading the kernel to the latest version available (2.6.29) with realtek driver support.

Php Not Updating After Php Update On Centos
Jul 14, 2009im trying to update my php version to 5.2+ so i can run phpmyadmin on my server. Ive tried two different methods both produced same results. First method was to download libxml2-2.7.3 and then do ./configure, make,etc then i download php, ./configure, make install, etc. At first i had to yum install make, then a c complier cause make and ./configure didnt work before that. After everything seemed to work fine until the end when it said you may have found a bug on php would you like to submit it? So obviously the php version didnt update at all.
Next i tried adding a repo that already contained php-5.2.5 and then yum install php since centos only seems to support regular yum install up to php version 5.1.6. i did rpm and installed php and thought sweet ive updated php. Ran php -v and i am still running php version 5.1.6.
CentOS Update Failing
Jun 25, 2008I'm having a problem with my CentOS 5 box. for some reason the update will not work.
I run yum update, The update starts, then when it gets too downloading the packages I get the following error for every single RPM.
[url]: [Errno 4] IOError: <urlopen error (114, 'Operation already in progress')> Trying other mirror.
The RPM's can be downloaded just fine if I copy and past that URL in my browser. I don't understand why the server can't open that URL
Does anyone know of a fix for this? Or is anyone else at iWeb having the same problem.
