Hi Guy, > Short version: > If a DRBD-controlled underlying block device (/dev/hda3, for example) > is mounted directly without DRBD running, the data is changed, then > DRBD is reinstated using that block device, will DRBD recognise the > changes? No, drbd will NOT recognise the changes without intervention; you'll need a fullsync to get into a consistent state. * shut down drbd on the secondary. * install & start drbd on the primary, make drbd primary. Secondary should still be down (to make extra sure you don't get a resync in the wrong direction). * with drbd mounted & primary on the node with the changed data, start drbd on the secondary. * issue drbdadm invalidate on the secondary to force a fullsync. Once that finishes you're back in business with consistent data on both nodes. Bye, Martin
