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
recover.c
Notes:
- 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.
recover.c
do_recovery
fence_victims
dispatch_fence_agent
agent.c
dispatch_fence_agent
use_device
run_agent
exec fence_XXXX
Regards.
