Sorry, I must be missing something, but I erased the entire device (i.e., dd if=/dev/zero of=/dev/dm-0), metadata, filesystem and all on all 3 nodes. How can this still be the problem? This is exactly what I did, on all three nodes: # dd if=/dev/zero of=/dev/dm-0 bs=128k dd: error writing '/dev/dm-0': No space left on device 573697+0 records in 573696+0 records out 75195482112 bytes (75 GB) copied, 160.872 s, 467 MB/s [root@sios0 ~]# drbdadm create-md r0 initializing activity log initializing bitmap (4484 KB) to all zero Writing meta data... New drbd meta data block successfully created. success [root@sios0 ~]# drbdadm up r0 0: Failure: (111) Low.dev. smaller than requested DRBD-dev. size. Command 'drbdsetup attach 0 /dev/dm-0 /dev/dm-0 internal' terminated with exit code 10 I even did "drbdadm wipe-md r0" in addition to the above, just to be sure. Is there some other option I need to specify for three nodes?
