from my rescue environment, I'd use: xfs_admin -u /dev/xxxx
(or the somewhat messier ext? equiv)
labels get messy too, when you have 27 systems and a half dozen file
systems each. you want your labels globally unique so if you plug a
volume into another system for repair there's no collisions. our
hostnames tend to be messy and nearly as unreadable as a uuid, so
embedding them in a label wouldn't actually be much help.
my install instructions for this server config ($job work in progress)
currently read...
mkfs.xfs -f /dev/sda1
uuid=$(xfs_admin -u /dev/sda1 | awk '{print $3}') # get the UUID
echo "UUID=$uuid /data xfs defaults 1 2" >> /etc/fstab
mkdir /data
mount /data
