I use XFS on Centos-4 here with 9500-S and 9550-SX. The load is quite heavy
(~30 climate modelling people) and the volume not tiny (~40 TiB). This system
works fine and I have no problems sleeping at night. But then again, if you
want data security you'll have to run backups anyway. Any filesystem can die.
This has already been stated in this thread, but it's worth saying again I
the i386/i686 kernel has 4k kernel stack, x86_64 has 8k, XFS does not like 4k
