Does this mean that "actvie" setting delays the delivery to the node of the message of the normal interface until the interface that failed becomes "faulty"?

Does it mean that the reconstitution of the cluster may happen until an inoperative interface becomes "faulty" by this delay?

If it is this phenomenon, I can understand a problem.

Because the number of the nodes that we treated was not so big, a big problem of "active" has not occurred.

I argue with a member and think about the use of future "rrp_mode".

Hideo Yamauchi.
