Which DRBD versions will connect and sync between each other.
Please note that we not extensively test or suggest that anyone run mis-matched DRBD between nodes for any extended period of time. We facilitate some backwards compatibility only to allow for a "rolling upgrades.
8.4 can talk to 9.0
9.0 can talk to 9.1
9.1 can not talk to 8.4.
