[Pacemaker] how stonith works

[Priyanka Ranjan]

Hi All,

suppose i am using ilo or any other stonith where one stonith cant shoot
more than one node , so i will have to create 4 stoniths for 4 node. assume
i am using 4 nodes cluster (node1, node2 , node3 and node4).

Lets say stonith-node1 is running on node 2 and stonith node-2 is running on
node1  .  we get a network failure which result node1 , node2 to be one
partiton  A and  node3 , node4 on other partion B

now i want to know how the partition B will be able to fence partition A  as
the stontih required  for stonithing  partition A  are not available  in
partition B , they are running in  partition A ( on node1 and node2) .

Thanks a lot in advance for your help,

Regards,
Priyanka.
