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

Wait. I just realized you're asking about centos *5* and XFS?

I wouldn't use XFS with EL5, root or not.... the XFS support was very

preliminary, the base kernel was just too old.

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
