xfs is now only available as an additional rpm, which can be used with either the plus or the distro kernel

The file you are looking for is in:

http://mirror.centos.org/centos/4/centosplus/i386/RPMS/

(or substitute x86_64 for i386)

and named: kernel-module-xfs-2.6.9-42.0.2.plus.c4-0.1-3.?????.rpm

(where ????? is the arch)

There are also smp, hugemem, largesmp, etc. kernels and has Karanbir said, there are also xfs modules for the normal kernels as well there.

This is required to get better XFS provided directly by SGI that is newer than the 2.6.9 code used by the upstream provider.

Thanks, Johnny Hughes

I installed kernel-module-xfs-2.6.9-42.0.2.EL-0.1-3.i686.rpm from the site you mentioned . But it is still unable to mount xfs filesystem at boot time.It gives following error.

mount: fs type xfs not supported by kernel

after booting up in 2.6.9-42.0.2.plus.c4 if i issue command "modprobe xfs" it gives an error about module not found.But following files are present on system.

/lib/modules/2.6.9-42.0.2.EL/extra/xfs.ko /lib/modules/2.6.9-42.0.2.EL/extra/xfs_quota.ko

You will notice that 2.6.9-42.0.2.plus.c4 is not the same as 2.6.9-42.0.2.

If all you needed the plus kernel for was xfs, then I would recommend you use the standard kernel alongside the standard-kernel-xfs-module package you already have installed.

What I have been doing on FC3 on my laptop where I need to read NTFS is to build my own kernel from the official src.rpm with a script imilar to this (the latest is probably on my laptop, and that's packed up ready to go):

It's way more elaborate than you need, and you, of course, wll need to add xfs.

You could also turn stuff off if you wish, but I'd not demodularise it lest initscripts breaks.

yes , I see it now.I used yum to install kernel-module-xfs and it installed the module for normal kernel only while i dont have that installed...

Yes, get the kernel-module-xfs for the centosplus kernel. It is in the centosplus repo.
