At least > I never observed problems with swap after server crash I can think about two cases at least when this is critical: 1) Live migration - if swap is corrupted live migration will fail. 2) DRBD consistency check - each time when the check find out-of-sync blocks you would need to calculate if they belong to swap or data disk. Also you will need to do disconnect/reconnect with shutting down one of DRBD nodes in case of master-master in order to resync and reset "oos" counter.
