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?
