I think you would need 8.3 and above for node stacking, also where is the 3rd node is it local or at a remote location. As far as upgrading goes. I would have thought this would be the best method. node1 = Primary node2 = Secondary 1) Stop DRBD on node2 ( Secondary ). Upgrade DRBD. Start DRBD on node2. Wait for DRBD to resync data 2) Once data has synced. Demote node1( Current Primary ) to secondary. Bring up node2 as your new Primary. 2) node1 is now a secondary, so your safe to stop DRBD, upgrade DBRD, bring back online as secondary and wait for resync to occur.....

My question is: Is it possible to add a third node as a DR server (act as a second secondary) using drbd version 8.2.5? Or will I have to upgrade to 8.3? These two servers are live at the moment and would rather not have to be taking them offline for a version upgrade. However, if this is the case, is there a "sure-fire" way to upgrading versions? Any help would be much appreciated.
