You mean like so? drbdadm primary <resource> mkfs -t ext3 /dev/drbd<num> tune2fs -l /dev/drbd<num> | grep UUID mount -U <uuid> <mountpoint> Will work in theory, but since both your DRBD device and its backing device are listed in /proc/partitions (which mount scans through for UUID mounts), mount will detect that UUID or both and get confused. So this is probably more error-prone than the conventional approach. Cheers, Florian -- : Florian G.
