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

Tue Sep 24 15:48:59 UTC 2013

I forgot to mention, OS is Debian Wheezy 64-bit, Corosync and Pacemaker
installed from packages via apt-get, and there are no local firewall rules
in place:

# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
