This was posted to the list earlier:
Your recommended approach for shrinking a DRBD device is this:
1. drbdadm down <resource> (on both nodes)
2. Shrink filesystem on underlying volume (on one node)
3. Shrink LV's (on both nodes)
4. Re-create DRBD meta data, drbdadm create-md <resource> (both nodes)
5. drbdadm up <resource> (both nodes)
6. drbdadm -- --overwrite-data-of-peer primary <resource> (on node
where you shrunk the file system)
