[Ocfs2-users] OCFS2 “Heartbeat generation mismatch on device” error when mounting iscsi target

[Sunil Mushran]

If ps aux|grep o2hb does not return anything, means you are using local
heartbeat.

That means you have mismatching ocfs2.conf file. And I suspect the node
where this is failing is the one that has the bad ocfs2.conf file. Compare
the config files from all the nodes and ensure it is the same. Or you could
simply replace the one on the failing node from another node. The file
should be the same everywhere. Remember to restart the cluster on that node.
