Hi
we have the same problem... :| we have RHE4 U2 with cluster suite 4
U2, in our case one node send a fenced to the other node, and we have
not succes to rejoining the node to cluster.
On logs appeared that node 2 cannot comunicate with node 1, but the
network connectivity is working fine
In a test we deleted the cluster.conf from node 2 and reboot it. After
the reboot the node got the last version of cluster.conf from node 1,
but still cannot joining to cluster again.
Below of this mail, we attached a little dump from node 1 that were the
cluster service is running.
Thanks in advanced for any help.
Best Regards,
Luis.G.

[node not joining cluster]
It would be interesting to know - though you may not want to do it - if the
problem persists when the still-running node is rebooted.
Obviously not at the moment, but I have a maintenance window upcoming
soon where I might be able to do that. I'll keep you informed about the
result.
Today I had the possibility to reboot the node that was still quorate
(i04-storage1) while the other node (i04-storage2) was still trying to
join.
When i04-storage1 came to the stage where the cluster services are
started, both nodes joined the cluster at the same time.
With this running cluster, I tried to reproduce the problem by fencing
one node but after rebooting this immediately joined the cluster.
Interesting. it sounds similar to a cman bug that was introduced in U3, but it
was fixed in U4 - which you said you were running.
Let's verify that then. I have the following RHCS related packages
installed:
ccs-1.0.7-0
rgmanager-1.9.54-1
cman-1.0.11-0
fence-1.32.25-1
cman-kernel-smp-2.6.9-45.8
dlm-kernel-smp-2.6.9-44.3
dlm-1.0.1-1
Yes, those look fine.
