Hi!
having a problem, I wonder what " corosync-cfgtool -s" does check actually:
I see on all nodes and all rings "status = ring 0 active with no faults", but
the nodes seem unable to comminicate somehow.
I there a kind of "corosync node ping" that actually checks that the local node
can communicate with another given node using the corosync (TOTEM) protocol?
The problem is that the cluster with three nodes says (h16 is the local node):
Node List:
* Node h18: UNCLEAN (offline)
* Node h19: UNCLEAN (offline)
* Online: [h16 ]
In syslog I get a message like this every few (consensus?) seconds:
Nov 20 07:46:59 h16 corosync[6240]: [TOTEM ] A new membership
(172.20.16.16:36752) was formed. Members

The cluster is brand new and has absolutely no resources set up.
