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.
Oh, yea, backups! :)
Heck, 30 users and 40 tibibytes of data is a pretty good stress test. How long have you been running XFS in this setup?
And how do you backup that much data?

To a tape library of course. IBM TSM or Veritas NetBackup.
If you need 40TiB of data, the backup is cheap.

This perticular system is just for scratch, filesystems mounted on the very descriptive /nobackup/...
But if I wanted to I could back it up using our IBM TSM system (fully incremental backup systems can take these kind of volumes).
