問題文
The usable capacity of a cluster reads zero although the hosts are powered on and high availability is enabled. Which condition explains that?
選択肢
- The high availability setting has been left at its default, because the default reserves the whole of the cluster until the number of failures to tolerate is entered.
- The buffer in the active policy has been set to the whole of the cluster, so nothing at all is left once the buffer has been taken off the total capacity.
- The storage of the cluster has been excluded from the capacity calculation, so the usable figure has no resource that it can report.
- The number of active hosts has been left below two, because a host sits in maintenance mode or cannot reach the leader of the cluster.
