Hi,
I configured a cluster of 2 RHEL6 nodes.
The cluster has only one HA service defined.
I have a problem with rgmanager getting stuck on shutdown when certain set of
conditions are met. The details follow.
1.
If I execute "shutdown -h now" on the node that is *not* running the HA service
then the shutdown process gets stuck with the last message in the
/var/log/messages being:
'date' my_node_name rgmanager[PID#]: Shutting down
The shutdown never completes, until I send terminate signal to the two
instances of the rgmanager process. Then shutdown completes normally.
2.
By comparison, if I execute "shutdown -h now" on a node that *is* running the
HA service, then shutdown proceeds normally.
3.
The problem walks with the absence of the service i.e. each of the two nodes
has the problem when the service is *not* running on it and does not have the
problem when the service *is* running on it.
4.
I have set the following debug level in the cluster.conf:
<logging>
<logging_daemon debug="on" name="rgmanager"/>
</logging>
But I am not getting any additional messages when the rgmanager is stuck during
shutdown.
Questions:
Is this a known problem?
How can I avoid it short of having some dummy service running on each node, as
a workaround?
Thanks and regards,
Chris Jankowski
