[ovirt-users] Ovirt 4.1 testing backup and restore Self-hosted Engine

[Alan Griffiths]

As I recall (a few weeks ago now) it was after restore, once the host had
been registered in the Manager. However, I was testing on 4.0, so maybe the
behaviour is slightly different in 4.1.

Can you see anything in the Engine or vdsm logs as to why it won't remove
the storage? Perhaps try removing the stale HostedEngine VM ?
