Hi Mike;
and, at first, thanks loads for your mail.

Yeah, I read about this and did this,all partitions to be used within
the array are type "FD". Even though this doesn't seem to change anything.

I'm hardly able to do any diagnostics on that since the information I
get is pretty limited. Basically, I created the array, xfs-formatted it,
put it into fstab and mounted it - worked well. Umounting, remounting
and everything worked as long as the array was running. After rebooting,
the array seemed gone. I don't get any useful error messages, just an
"XFS SB error" when trying to mount the array (which is not running at
this time), and when I try to start the array (mdadm -R /dev/md0), I
just get something like "/dev/md0 has no devices" (though the real
behaviour and message changes differing with the kernel version used).
Cheers,
Kris
