Failed to remove node ( Failed to remove node )

have very good morning.
sorry for the inconvenience, but something happened to me, I have 2 servers currently Proxmox version 3 I was connecting a third server to the cluster and I fault the electric fluid and apparently not complete the entry node to the cluster, now are giving me problems. ..
when I try to delete the cluster I get this error. (/ $ Pvecm delnode meduza-III
cluster not ready - no quorum?

cman restart the service and I get this ...

/ $ / Etc / init.d / cman restart
