[CentOS] UC centos 5 with xfs root?

There are 3 issues here: Grub, the kernel and RedHat.

1) Grub won't run in an XFS /boot partition, but will happily run
xfs_state1_5 to boot from an XFS root partition.
2) The kernel has supported XFS quite happily since at least 2005, I am
looking at an SGI Propack 4 manual of February that year and it states
that SLES 9 SP 1 contains the kernels with XFS support.
3) May be an issue.

I'm just closing down an old Altix (2004 vintage) and that has always
run XFS for everything except /boot.  In the early days it used RedHat,
but SGI's software included a patched kernel.  Later on it ran SuSE
Linux out-of-the-box.  For compatibility I've configured the x86
machines with OpenSuSE 9 onwards as EXT2 for /boot and everything else
on XFS.

Sorry to mention SuSE on a CentOS NG, but that's where my experience lay
at that time!

Regards,

Martin

That's not completely true - XFS existed in the Linux kernel before EL5
- however, RedHat's support of XFS was added to the EL 5.4 kernel with a
backport of a contemporary XFS release - and has had fixes added in
subsequent EL5 kernels

However, I would agree that unless you have a very good reason for
staying with CentOS 5, then using CentOS 6 would be better - regardless
of XFS support
