Live migration of server with attached volume in state backing-up
Currently a server cannot be live migrated if a attached volume is in state 'backing-up'. This is due to some drive limitations, but some backup drivers working with snapshots should be able to live migrate a server with a volume in status 'backing-up'.
The request to live migrate a server is handled via the nova api but the the state of the volume(s) is checked via cinder
and throws following exception:
ERROR nova.compute.
nova.exception_
available or downloading to reserve, but the current status is backing-up.
The suggestion is to retrieve additional valid states for volumes for different methods from the configured backup-driver to enable more functionality of the backup drivers.
