[Linux-cluster] Manual Fencing problem

[Mauro Casiraghi]

Ok i think that it works but now i have another problem

On the node0 messages i can see the follow message


fence_manual: Node node1 needs to be reset before recovery can procede.
Waiting for node1 to rejoin the cluster or for manual acknowledgement that
it has been reset (i.e. fence_ack_manual -n node1)
so i try to fence_ack_manual -n node1

and i recived this message

fence_ack_manual -n node1
Warning:  If the node "node1" has not been manually fenced
(i.e. power cycled or disconnected from shared storage devices)
the GFS file system may become corrupted and all its data
unrecoverable!  Please verify that the node shown above has
been reset or disconnected from storage.
Are you certain you want to continue? [yN] y
can't open /tmp/fence_manual.fifo: No such file or directory

Thank you for your help

Best Regards
