This is a RAID (md) -- i.e., device, UUID. Think of it
as of disk drive serial number for example -- look at
/dev/disk/by-id/.

And mount expects *filesystem* UUID, not a device UUID.
I.e., the UUID which was written by mkfs. For a ext[234]fs,
tune2fs -l /dev/md0 will show it; for other filesystems
use appropriate tools.
