Public bug reported:

Version: stable/juno

Bug description:
In the view of "Volumes", provided that some volume whose status is "in-use" or it is being attached to a VM. If the associated VM is deleted, this will trigger the detaching of the volume. If the volume detaching process is failed by whatever reason, then the volume becomes attached to an already-deleted VM. On Horizon, we now can see the info for example of "Attached to None on /dev/vdb" in the column of "Attached To".

If now, we try doing "Edit attachments" (for example, in order to detach
the died VM) then Horizon dashboard always pop up the error of "Error:
Unable to retrieve volume information" and the purpose of detaching is
aborted.

Proposal:
Such an error has to be disabled and the process of "Edit attachments" should be continued.
