Public bug reported:
Attempt to boot a server with a block device mapping that includes a
boot volume created from an image, plus an existing data volume. If the
boot-volume creation fails, the data volume is left in state "in-use",
attached to the server which is now in "error" state". The user can't
detach the volume because of the server's error state. They can delete
the server, which then leaves the volume apparently attached to a server
that no longer exists. The only way out of this is to ask an
administrator to reset the state of the data volume (this option is not
available to regular users by default policy).
The easiest way to reproduce this is to attempt to create the boot
volume from qcow2 image where the volume size is less than the image
(virtual) size.
