Thank you for the replies. The problem was really one server which shouldn’t

As said in the title, when I want to mount a iSCSI target on one machine I get
the following error:
(o2hb-3F92114867,7826,3):o2hb_check_own_slot:590 ERROR: Heartbeat generation

Still the same error if i try to mount the iSCSI disk:
o2hb_check_own_slot:590 ERROR: Heartbeat generation mismatch on device (sdb):
expected(2:0x2f32486d4c54730a,
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
