Hi, I am trying to move block storage between servers with different storage types, one using iscsi and the other rbd, individually they work fine. nova version is 2:12.0.2-0ubuntu1~cloud0. Of course I have checked with attached and detached blocks for these tests.
I see both pools: cloud:~ # cinder get-pools +----------+---------------------------------------------+ | Property | Value | +----------+---------------------------------------------+ | name | cloudvolume@iscsi-cloudvolume#iscsi | +----------+---------------------------------------------+ +----------+---------------------------------------+ | Property | Value | +----------+---------------------------------------+ | name | rbdvolume@rbd-cephvolume#rbd | +----------+---------------------------------------+ running: #cinder migrate <vol_id> rbdvolume@rbd-cephvolume#rbd I see this error in cinder-schedule.log 2016-05-04 10:32:18.397 28665 ERROR cinder.scheduler.manager [req-609fb633-6c1d-419b-a0d7-193d10a0732a 6e57d91da967475b887ef485ca4db611 276c19f252d24f0ebe0aa9ff39307f56 - - -] Failed to schedule_migrate_volume_to_host: No valid host was found. Cannot place volume cc23af33-586c-4e0d-b248-127aef26acfd on rbdvolume@rbd-cephvolume#rbd Then I checked using retype instead of migrate for different backend types (iscsi and rbd): #cinder retype <vol_id> rbd show this log: 2016-05-04 10:45:04.506 28665 ERROR cinder.scheduler.manager [req-5c7066bf-6fb7-484c-9c95-25cd9508f381 6e57d91da967475b887ef485ca4db611 276c19f252d24f0ebe0aa9ff39307f56 - - -] Could not find a host for volume cc23af33-586c-4e0d-b248-127aef26acfd with type cc8705d5-98cb-4071-bd63-7440a5f95138. using --migration-policy on-demand flag there is no error in scheduler log, but there is no migration either. Any Idea?
