This is for the archive, as well as anyone who cares, but I recently ran
into an interesting XFS bug.

xfs_db -r /dev/root
xfs_db: sb 1
xfs_db: print uuid
uuid = 9d44dc2e-9363-1024-8e23-080069124456
xfs_db: 

What you see above is a normal filesystem output.  What I was seeing was
amanda reporting xfsdump exiting on signal 1 for that filesystem.  A
support call to SGI and they pointed out my problem.  There's a bug that
SGI hasn't managed to reliably reproduce (and thusly squash) which causes
uuid to be set to null on very rare occasion (this is the first time I've
seen it in 5+ years dealing with XFS).  You can run xfsdump with the -J
flag and dump the filesystem, but the only real fix is the dump the
filesystem, mkfs it, and restore the data.  Running xfsdump on the command
line returned no value at all that was reported.  It just exited to the
command line after it estimated the dumpsize for the filesystem in
question.  Using -J worked fine.
