Quoting Jaap Winius <jwin...@umrk.nl>:
Very interesting. I'm already running DRBD 9, so that base has already been covered, but here's some extra information: My test system actually consists of a single 4-node DRBD cluster that spans two data centers, with each data center having a 2-node Pacemaker cluster to fail resources over between the two DRBD nodes in that data center. But, for the purpose of quorum arbitration I guess these extra DRBD nodes don't matter, perhaps because four is not an odd number?
No, four nodes are enough and I eventually figured it out. There was an extra firewall port that may have helped (2224), but I suspect that the main problem was that I forgot to enable the SELinux boolean for DRBD: daemons_enable_cluster_mode=1. Now everything is working perfectly.
Thanks, Jaap _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
