  • Closed as program error.

Error description

  • If the database in a single-node cluster becomes corrupted, we
will fail over to the secondary copy, which is guaranteed to be
wrong. If the cluster has always been single-node, the backup
copy will be empty. If the cluster was reduced to single-node,
the backup copy will be a stale snapshot from the time when the
cluster was reduced.
