Just to add some positive feedback: I implemented XFS on an x86_64 box running
CentOS around here. The machine is an NFS, Samba and Emailserver (kolab, that
means postfix + cyrus imapd). The machine has a Hardware SCSI RAID with 8 10k
U320 HDs. So far we had a minor issue with some small undeletable files that
could be tracked down to a XFS bug (which is fixed by now). Other than that
the box has been running rock stable. We started with CentOS 4.2 or 4.3 and
are now at 4.5 via continuous yum updates.
Before the machine went into production I had about two weaks for doing heavy
benchmarking and some reinstalls. Using XFS and tuning the parameters of the
RAID array gave a massive performance boost. I also tried tuning ext3 but got
only about half the throughput than with XFS, so I decided to go XFS.
Of course these results depend on usage pattern, hardware, etc. So do your own
benchmarks. I myself asked our heavies nfs users for their homedirs or parts
of it and benchmarked by copying these around in parrallel. This was quite
enlightening and much more useful than artifical benchmarks.
