I have a CentOS 5.2 box with 2.6.18-92 kernel. I would like to upgrade the kernel, but not to the latest available version. How can I pull out a specific patch and apply it? Any help?
Thanks, CS.

This information should be helpful in rebuilding the kernel "the CentOS way": http://wiki.centos.org/HowTos/Custom_Kernel
HTH, Filipe
you could head to http://www.howtoforge.com and find the *"Compiling the Kernel the CentOS way"*

Second: for CentOS related subjects, how can one expect something in howtoforge (or anywhere else) to be better than content in the CentOS Wiki?
Especially in the case of that specific page, which I know is regularly kept up to date and will reflect newer versions of the kernel shipped with CentOS...

I can only agree with Filipe ... :-D

I am sorry for the miss understanding, I really agree to that too, but it is just that i thought you could have an alternative like the one I read in the http://www.howtoforge.com which actually just talked about downloading a vanilla kernel and applying your patch and them making an rpm version so you could run on other systems.

Call me stupid.
just wondering, why would you not want the latest kernel?

Because it will potentially not run "as smooth" as the kernel version shipped by CentOS. While newer kernels typically improve hardware support, they also introduce changes that are incompatible with the userland utilities provided in CentOS, so these changes may actually *break* something that works with an older version...
It's all part of what is called an "Enterprise Linux Distribution". When you choose such a distribution, you basically accept that some of your packages will be somewhat outdated (with backports for security issues) but on the other hand you know the components have been more tested together than with other "bleeding edge" distros... If you want to run a more updated kernel, you should probably look into Fedora or Ubuntu. If you want to run *the* latest kernel, you should probably look into Gentoo. However those are admittedly not as stable as CentOS/RHEL is.
HTH, Filipe

sorry for the confusion

I am trying to build a Lustre file system over CentOS. The file system server's kernel needs to be lustrized, however client can be installed without altering kernel. I was struggling with client installation and thought specific kernel requirement might be an issue. I am stil not sure why is it failing though... Anyway, to cut it short, needed for some dependency issues..

looks like Lustre has very specific kernel requirements, see http://wiki.lustre.org/index.php/Lustre_Support_Matrix
eg, Lustre 1.8.0 -must- be run with kernel 2.6.18-92.1.17.el5 and not, for example, 2.6.18-92.1.18.el5
I am a newbie and do not know as much in detail abt packages. However, I noticed something strange while installing gcc. I started with bare minimum 'no-base' install with a kickstart file, so I didn't have gcc in it. Later, when I installed gcc the 'kernel-headers' packages was marked to be updated to 2.6.18-128.1.10.el5 for dependency issues.
Here is a summary: ============================================================================= Package Arch Version Repository Size ============================================================================= Installing: gcc i386 4.1.2-44.el5 base 5.2 M Updating: glibc i686 2.5-34 base 5.2 M glibc-common i386 2.5-34 base 16 M libgcc i386 4.1.2-44.el5 base 94 k
Installing for dependencies: binutils i386 2.17.50.0.6-9.el5 base 2.9 M cpp i386 4.1.2-44.el5 base 2.7 M glibc-devel i386 2.5-34 base 2.0 M glibc-headers i386 2.5-34 base 598 k kernel-headers i386 2.6.18-128.1.10.el5 updates 917 k libgomp i386 4.3.2-7.el5 base 67 k
However, the kernel is 2.6.18-92.el5. The mismatch in kernel and kernel-headers is confusing me. Any insights?
Thanks, CS.

You are not the first to be confused by that - it is almost a FAQ on the forum; however it is the expected behavior - yum will install the latest version of a package available and kernel-headers does not depend on the kernel version. You should be able to use "rpm -i --oldpackage ..." to install the version matching your kernel.
