Hi,

We've been testing our cinder driver extensively and found a strange
behavior in the UI:
- when trying to delete a snapshot that has clones (created volume from
snapshot) and error is raised in our driver which turns into
"error_deleting" in cinder and the UI; further actions on that snapshot are
impossible from the ui, the user has to go to CLI and do cinder
snapshot-reset-state to be able to delete it (after having deleted the
clones)
- to help with that we implemented a check in the driver and now we raise
exception.SnapshotIsBusy; now the snapshot remains available (as it should
be) but no error "bubble" is shown in the UI (only the green one: Success.
Scheduled deleting of...). So the user has to go to c-vol screen and check
the cause of the error

So question: how should we handle this so that
a. The snapshot remains in state "available"
b. An error bubble is shown in the UI stating the cause.

Thanks,
Eduard
