Hello Digimer and Kaloyan

Thank you for your information.

I'll set gfs1, gfs2 and gfs3 with lowest ID (ex, 1,2,3).

I found the following Notes in fenced/recover.c


   - When fenced is started, the complete list is initialized to all
   the nodes in cluster.conf.
   - fence_victims actually only runs on one of the nodes in the domain
   so that a victim isn't fenced by everyone.
   - The node to run fence_victims is the node with lowest id that's in both
   complete and prev lists.
   - This node will never be a node that's just joining since by definition
   the joining node wasn't in the last complete group.
   - An exception to this is when there is just one node in the group
   in which case it's chosen even if it wasn't in the last complete group.
   - There's also a leaving list that parallels the victims list but are
   not fenced.

Here is call procedures.


        exec fence_XXXX
