Comment 2 for bug 2028642

Hi Chuan!

Thanks for raising this bug report. We discussed this at a weekly IRC meeting and have a couple of questions:

1) Can you please share the migration command you used? we're interested to know if you're performing a nondisruptive share migration; where we believe manila is cleaning up the share servers immediately: https://github.com/openstack/manila/blob/3b9cfe126fbb5d83febe6f9f8747be3c4ce787c4/manila/share/manager.py#L5823-L5839
Otherwise, it could take some time for the share server deletion routine to pick up the share server and delete it.

2) How do you plan to rollback? If a nondisruptive migration occurred, we expect that the storage system doesn't have the share server in the original host; and a rollback would really be a different migration operation.
