It means that cman could not create the local socket in /var/run for
communication with the cluster clients.

cman tries to create /var/run/cman_client & /var/run/cman_admin - things like
cman_tool/groupd/ccsd etc talk to cman over this link. If it can't be created
then its not much use.

Check /var/run is writable and able to hold Unix domain sockets.
