vDisk is not attached to any StorageRouter

Want to try some luck on any reply.

I run mds_checkup and found some vdisks fail on ensure_safety.

In [5]: vdisk.info['live_status']
Out[5]: 'RUNNING'

I tried to stop_object or restart_object but got :

In [6]: vdisk.storagedriver_client.stop_object(str(vdisk.volume_id), False)
---------------------------------------------------------------------------

Any idea please?

How can I remove this vdisk? Its failure on safety check prevents snapshots from being scrubbed.
