I assume corosync is hanging. On the console I see
'Waiting for corosync services to unload: ...'

The problem seems to be a resource that takes to long for stopping. In 
that case the resource is set to unmanage and is blocking corosync.

Is there a general possibility to get informed if a resource is changing 
the state to unmanage ? Other state changes I observe via ClusterMon. 
But the state change to unmanage is not reported.

Kind regards,
Detlef
