Nothing special here you just benefit from compression and snapshot of the underlying zfs layer.</div><div class="gmail_extra" dir="auto"><br></div><div class="gmail_extra" dir="auto">With zfs over drbd you need to think about resource failover ie the zfs resource needs to be exported from one node and imported to the other one , something that pacemaker can handle for you for example. You also can't have dual primary in this case, you can't have zfs pool imported on two servers in same time.</div></div>
