[Pacemaker] Corosync won't recover when a node fails

[David Parker]

Hello,

I have a 2-node cluster using Corosync and Pacemaker, where the nodes are
actually to VirtualBox VMs on the same physical machine.  I have some
resources set up in Pacemaker, and everything works fine if I move them in
a controlled way with the "crm_resource -r <resource> --move --node <node>"
command.

However, when I hard-fail one of the nodes via the "poweroff" command in
Virtual Box, which "pulls the plug" on the VM, the resources do not move,
and I see the following output in the log on the remaining node:

Sep 24 11:20:30 corosync [TOTEM ] The token was lost in the OPERATIONAL
state.
Sep 24 11:20:30 corosync [TOTEM ] A processor failed, forming new
configuration.

Those last 3 messages just repeat over and over, the cluster never
recovers, and the resources never move.  "crm_mon" reports that the
resources are still running on the dead node, and shows no indication that
anything has gone wrong.

Does anyone know what the issue could be?  My expectation was that the
remaining node would become the sole member of the cluster, take over the
resources, and everything would keep running.

For reference, my corosync.conf file is below:

compatibility: whitetank

totem {
        version: 2
        secauth: off
        interface {
                member {
                        memberaddr: 192.168.25.201
                }
                member {
                        memberaddr: 192.168.25.202
                }
                ringnumber: 0
                bindnetaddr: 192.168.25.0
                mcastport: 5405
        }
        transport: udpu
}

logging {
        fileline: off
        to_logfile: yes
        to_syslog: yes
        debug: on
        logfile: /var/log/cluster/corosync.log
        timestamp: on
        logger_subsys {
                subsys: AMF
                debug: on
        }
}


Thanks!
Dave
