Problem

A failback operation may not be able to complete if a host in the cluster is offline or faulty.

Example of a problem completing failback.

Issue

Failure Scenarios

The following scenarios illustrate cases that result in the failure of the failback operation.

Faulty Node

In a multi-node cluster, if one node is faulty then failback will not start.

IO Filter Unavailable

In a multi-node cluster, all hosts are healthy but one node's IO filter is unavailable. Failback will not start.

Success Scenarios

Maintenance Mode

In a multi-node cluster, all hosts are healthy but one host is in maintenance mode. Failback will be able to continue.

Faulty Host Corrected

In a multi-node cluster, one host is faulty and that faulty host is replaced with a healthy host. Failback will be able to continue.

Faulty Host Removed

In a multi-node cluster, one host is faulty and that faulty host is removed from the cluster (removed from inventory). Failback will be able to continue.
