Hi, DRBD ships with a script called snapshot-resync-target-lvm.sh that does just that, that can be called before/after resync. In our config we use : before-resync-target "/etc/scripts/snapshot-resync-target-lvm.sh -p 15 -- -c 16k"; after-resync-target /etc/scripts/unsnapshot-resync-target-lvm.sh; Please make sure you get the latest version of the script, because the one shipped in ubuntu 10.04 (DRBD v8.3.7) is buggy and goes into an endless loop. Also, only a recent kernel will let you merge the snapshot back into the main volume. Lionel Sausin.
