[Ocfs2-users] OCFS2 “Heartbeat generation mismatch on device” error when mounting iscsi target
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 mismatch on device (sdb): expected(2:0xa0cf28215b4b1ed3, 0x54d8a036), ondisk(2:0xb016e6a72676a791, 0x54d8a037) The same iSCSI target is working on other machines. Any idea what this error means?? --? Danijel Krmar A51 D.O.O. Novi Sad https://www.activecollab.com/ -------------- next part -------------- An HTML attachment was scrubbed...

On node 2, do: ps aux | grep o2hb I suspect you have multiple o2hb threads running. If so, restart the o2cb cluster on that node.
