Sorry, for jumping this thread, but I'd like to add a few cents here.

XFS is great, fast and quite reliable as long as you can ensure that the
file system is never ever crashing (or the hardware beneath it). XFS has
the top priority to keep the system as is intact, but sacrifices the
integrity of single files for that, i.e. after a hard crash, you might
find files with one or more 4096 byte blocks with just zeros. This might
be ok for you, but most of the time isn't.

Lesson learned from that:
If you run XFS, use it on good hardware with some failure protection
(e.g. ECC memory, RAID-level 1,5,6, etc).
