[Linux-cluster] Clusterbehaviour if one node is not reachable & fenceable any longer?

[Nicolas Kukolja]

Hello,

I have a cluster with three nodes (rhel 5.5) and every server has an
ipmilan-module configured as fencing device in my cluster-config.
Now, if one of the nodes is not reachable and its fencing device is not
reachable, too, then the other two nodes try to fence this node again and
again... without stopping it.

Only when this node is reachable (& fenceable) again, the fencing proceeds
sucessfully and the cluster service moves to another node.

Why does the service not move to another node earlier? I think, its a
common error scenario, that one node and its fencing device are not
reachable maybe due to power problems e.g.
How do I have to change the cluster configuration to retrieve my expected
behaviour?

Thanks in advance for any suggestions...

Kind regards,
Nicolas
