Where could this problem come from ? How can I avoid this eviction of node ? Any help would be very appreciated .You haven't posted any cman/openais messages but it's quite possible you've hit this bug: https://bugzilla.redhat.com/show_bug.cgi?id=485026 There's a patch included and some links to fixed RPMs. Chrissie if I'm misunderstanding, to be more on the problem of starting a second node too late with regard to the start of a first node ... so that in fact the second node can't enter in the cluster anymore. But there are no "Node is undead" messages in the syslog in this case (I've checked the joined syslog in the bugzilla). My problem is after a poweroff -f on a node of a ha pair with quorum disk but when both nodes are up and running their services : in this case , making a poweroff on second node makes the first one generate the loop "Node 2 evicted" and "Node 2 is undead" in syslog, and this even just after the poweroff, not when the second node is trying to start the CS again .
