It looks like you have one PDU for both nodes. If that is the case, be aware that the PDU is a single point of failure. Also be sure that the power cables never get moved or you will get a false-positive fence, which could be disastrous. Do the nodes not have IPMI that you could use a primary fence method with the PDU as a backup method? > Fencing Levels: > > > > Location Constraints: > > Ordering Constraints: > > Colocation Constraints: > > > > Cluster Properties: > > cluster-infrastructure: classic openais (with plugin) > > dc-version: 1.1.9-2.2-2db99f1 You should really upgrade to 1.1.10 or newer. > expected-quorum-votes: 2 > > no-quorum-policy: ignore > > stonith-enabled: false Very, very bad. This means the PDU fencing, though defined, will never be used. You must enable this (and test crashing both nodes!) in order to prevent split-brains. > Michelle Streeter -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education? _______________________________________________ Users mailing list: [email protected] http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
