Public bug reported:
When using Ceph as the back end storage a snapshot of a volume is
dependent upon the original volume meaning it is an illegal operation to
delete the volume without first deleting the snapshot.
Should you try and delete such a volume horizon {kilo} reports back the
error "Error: You are not allowed to delete volume:" - This error
message is confusing and leaves the end user unsure why the volume can
not be removed.
I think we should handle this by better checking what cinder API reports
back and displaying a more user friendly error message.
The below is an example of the error that comes back from cinder,
passing this up in horizon would be very helpful.
$ cinder delete 34feea60-fb50-4fbe-8136-885f5553a8a8
Delete for volume 34feea60-fb50-4fbe-8136-885f5553a8a8 failed: Invalid volume:
Volume still has 1 dependent snapshots. (HTTP 400) (Request-ID:
req-320be24f-ce7a-4a79-9d6f-9166821c42e9)
ERROR: Unable to delete any of specified volumes.
