The upstream bug was fixed back in March 2014. |
Description of problem: On an AIO installation, the cinder is configured with multiple back ends: Netapp & LVM. A volume, 10 GB size, was created on the Netapp back end, (the back end was picked by the cinder-scheduler, not by the user). I ran the migration command: # cinder migrate <volume-id> <hostname>@lvm after the migration failed two volumes appear in the cinder volume list: +--------------------------------------+-----------+--------------+------+-------------+----------+-------------+ | ID | Status | Display Name | Size | Volume Type | Bootable | Attached to | +--------------------------------------+-----------+--------------+------+-------------+----------+-------------+ | 405406a0-21e9-4a7b-baff-daaceed191fa | available | None | 10 | None | false | | | 4499979e-c326-4150-b3d6-2cbbbf9642c6 | available | None | 10 | None | false | | | fabdfd8b-c6e7-4f2f-a93e-60cd4556ed57 | available | None | 1 | None | false | | +--------------------------------------+-----------+--------------+------+-------------+----------+-------------+ but there's only one volume with 10 GB, and that's the one in the Netapp storage, there's no volume in Cinder's LVM back end. The migration failed with the error (from volume.log): 2014-03-25 17:54:12.355 6722 ERROR cinder.openstack.common.rpc.amqp [req-a58b365a-8e1f-434b-b5b3-dc33014ea12c None] Exception during message

create a volume on the Netapp back end (without associate the volume with a type to the back end). 2. migrate the volume to the LVM back end. 3. Actual results: The migration failed and there's a false data in the cinder volume list. Expected results: the migration should succeed - there should be 1 volume in the destination back end.
