Having had an O2 with IRIX on my desk for 4 years until 2003,
I came to love XFS.  Until this year, I've used it happily on all
my Linux boxes, with the /boot exception.  (I haven't found a
boot loader that can read XFS.  How did IRIX do it?)

However, I've had two serious issues this year, which I never
got to the bottom of, but which went away when I moved to

The first was repeatable NFS hangs from a variety of Linux &
Solaris clients when the exported filesystem was XFS.

The second was occasional rsync hangs when writing to a XFS
filesystem (we use rsync for backups, 100G per day).

These don't mean that XFS is the culprit, but I'm now nervous.
I still use it myself, but if someone asks which filesystem they
should choose, it's no longer the automatic answer.
