That's strange, I hardly think it's related to qdiskd.
Maybe check 'cman_tool version' on both and ensure that the cluster.conf
version matches the output of 'cman_tool version' - that's a common way
to prevent the cluster from forming on RHEL4.
If they're out of sync:
* get the right cluster.conf in place & bump the config version #
* run 'cman_tool version -r <new_config_version_#>'
* copy cluster.conf to other node
Note: Restoring the nodes to the same package versions will have utterly
no effect if the config version is out of sync!
