[sheepdog-users] Force cluster to start with a missing node

[Valerio Pachera]

Think of this situation:
we stop the cluster for do some maintenance.
We find out that a node has hardware problems and we do not want (or
can't) use it again.
We are also unlucky (and not provident) and have no server to substitute.

The cluster will refuse to start with a missing node.
Is it possible to force it to start?
