Hi Andrew,

Thank you for comment.

My understanding may be wrong.

When stonithd accesses memberlist, stonithd can know node configuration.
It is from memberlist and does not understand which node can carry out STONITH.
Only stonithd of each node knows an STONITH list of nodes to have.

Or would you commented in a meaning to judge the number of the configuration of the cluster from
memberlist?

Best Regards,
Hideo Yamauchi.
