I believe you will want to investigate the "clean_start" property in the fence_daemon stanza (RHEL 5). Unsure if it is in RHEL6/Cluster3 code. It is my understanding that the property can be used to by-pass the timeout and remote fencing on initial startup. This assumes you know that the remote

Gianluca, I thought that the sequence when both nodes are down and one starts was: a) Fence daemon notices that the other node is down (with status option of the fence command) b) Fence daemon waits for the configured amount of time, based on cluster.conf values or default ones, to "see" the other

Thank you Bob; That is a very good point about the file-system being mounted on the other node. I have opened a ticket with Red Hat on this issue, and have not gotten a satisfactory reply. I was told that an "fsck" should be performed at boot from Red Hat support. I am still finding that the kno

Hi, I have the same situation (two_node=1, RHEL5.5, no quorum disk), but it works nice for me. Having both nodes down, starting one node always sucessfully fence the other and this is the expected as Fabio said. In my scenario the fenced node must remain down, even when sucessfully fenced by
