    Recently I had a power failure in the server room, after that all the servers started successfully and worked for two days without errors. But a day ago all the nodes in my cluster became red.
    I used my old simple script to restart all the needed services like this:

    service pvestatd stop
    service pvedaemon stop
    service cman stop
    service pve-cluster stop
    sleep 2
    service pve-cluster start
    service cman start
    service pvestatd start
    service pvedaemon start
    Earlier this simple script did all the job if the cluster sometimes begun to behave incorrectly.
    But now the cman service cannot stop, it hangs with the message:

    root@srv-bld-a07:~# service cman stop
    Stopping cluster: 
       Stopping dlm_controld... [  OK  ]
       Stopping fenced... [  OK  ]
       Stopping cman... [  OK  ]
       Waiting for corosync to shutdown:[  OK  ]
       Unloading kernel modules... [  OK  ]
       Unmounting configfs...
    I need to press Ctrl+C to abort the process. After that cman starts without errors
    Is there anything I can do with that?

    Here is the cluster config:

    I suggest you update to latest version and test again.

    The problem solved.
    The NFS share was unavailable. Therefore cman halted on "unmounting configfs..."
