DRBD 8.0.6 / HEARTBEAT 2.0.8-4 I'm having some problems resizing and I'm sure what I've done wrong will be obvious to someone. I have XFS filesystem on top of a drbd, on top of an LVM. To expand I'm doing 'lvextend /dev/vg0/home -L +128M' and 'drbdadm adjust home' on both nodes first. Once that's done I'm doing xfs_grow /dev/drbd0 on the primary node only. It seemed to work the first time but just to make sure I did it a couple more times and it breaks drbd0. df isn't showing the increased size and if I restart drbd it won't come up and gives this message: Failure: (119) No valid meta-data signature found. ==> Use 'drbdadm create-md res' to initialize meta-data area. <== Command 'drbdsetup /dev/drbd0 disk /dev/vg0/home /dev/vg0/home internal --set-defaults --create-device --fencing=resource-only --on-io-error=detach' terminated with exit code 10 I put the meta data on a separate lvm and that seems to keep the meta data from having problems but before I can grow the xfs filesystem I have to restart the cluster to get the drbd to re-sync? (ON BOTH NODES) lvextend /dev/vg0/home -L +128M drbdadm adjust home heartbeat stop drbd stop drbd start heartbeat start (ON THE PRIMARY ONLY) xfs_grow /dev/drbd0 Does this sound correct or is there a way to get drbd0 to re-sync without restarting the whole cluster? It only took 30 seconds for the cluster to restart but I'd rather not have to interrupt users in the middle of the day if I need to expand some space. Can anyone point me to some docs on this?
