It looks the following

CMAN: forming a new cluster
CMAN: quorum regained, resuming activity
CMAN: sendmsg failed: -13
CMAN: No functional network interfaces, leaving cluster
CMAN: sendmsg failed: -13
CMAN: we are leaving the cluster.
CMAN: Waiting to join or form a Linux-cluster
CMAN: sendmsg failed: -13
CMAN: sendmsg failed: -13
CMAN: sendmsg failed: -13
CMAN: sendmsg failed: -13
CMAN: sendmsg failed: -13
CMAN: forming a new cluster
CMAN: quorum regained, resuming activity
CMAN: sendmsg failed: -13
CMAN: No functional network interfaces, leaving cluster
CMAN: sendmsg failed: -13
CMAN: we are leaving the cluster.
CMAN: Waiting to join or form a Linux-cluster
CMAN: sendmsg failed: -13

Can't interpret the "No functional network interface". No firewall is
running on the system. /etc/hosts.{allow,deny} makes no restriction. The
/etc/hosts file is set up correctly.
