       fence_ack_manual - a program to override fenced fencing operations


       fence_ack_manual [OPTIONS] nodename


       When  fenced(8) fails to fence a node, it retries indefinately.  fence_ack_manual(8) tells
       fenced to stop retrying and consider the node fenced.

       It is important that this only be done after the node has  been  manually  turned  off  or
       prevented  from  writing  to shared storage.  Without this manual action and verification,
       the storage that fencing protects may become corrupted.

       When fenced fences a node that has no fence devices defined in the cluster  configuration,
       the   fencing   operation  fails.   This  failure  will  be  repeated  indefinately  until
       fence_ack_manual is run by an operator to indicate the node is in a safe state to proceed.
       (Defining no fencing devices for node is the equivalent of using the fence_manual agent in
       previous versions.)
