Though usually people don't directly refer to /dev/dm-X, but to the "logical name" (devicemapper minors are not stable). So I'd expected a /dev/mapper/vg-lv or /dev/vg/lv to be used instead of /dev/dm-0. Can you post a "transscript"? Volume group scratch, LV name s0: VG=scratch LV=s0 size_gb=75 lvcreate -n $LV -L ${size_gb} $VG # zero out first and last megabyte; # if you prefer, just leave off -o and -l, to zero-out all of it. blkdiscard -v -z -o 0 -l 1M /dev/$VG/$LV blkdiscard -v -z -o $(( ${size_gb} * 2**30 - 2**20 )) -l 1M /dev/$VG/$LV Make your config file refer to disk /dev/$VG/$LV dmesg -c > /dev/null # clear dmesg before the test drbdadm -v create-md # on all nodes drbdadm -v up all # on all nodes dmesg # if it failed drbdsetup status -vvs drbdsetup show *now* do the mkfs on drbd, once, on one node. -- : Lars Ellenberg : LINBIT | Keeping the Digital World Running : DRBD -- Heartbeat -- Corosync -- Pacemaker DRBD® and LINBIT® are registered trademarks of LINBIT __ please don't Cc me, but send to list -- I'm subscribed _______________________________________________ Star us on GITHUB: https://github.com/LINBIT drbd-user mailing list drbd-user@lists.linbit.com http://lists.linbit.com/mailman/listinfo/drbd-user
