Hi guys, I'm facing a problem with Cinder version openstack-cinder-2014.1.3-1 which doesn't let me migrate a volume from one LVM backend to another LVM. I'm doing this simple task:
- cinder create lad-test-02 20 - cinder migrate lad-test-02 newcinderhost050 The logs show that the process begins, the iSCI target is created and the LV too on the new host. Unfortunately the old target/LV persists, it isn't deleted... A Cinder list shows: | 0f70ccb6-85ba-4726-bda8-4051b68e943e | available | lad-test-02 | 20 | None | false | | 239bab9d-a70c-470e-ad13-9100946d8ca7 | available | lad-test-02 | 20 | None | false | tgtd-admin -s and lvs, issued on the old and the new Cinder hosts, demonstrate that the two volumes are present and running at this level. If i try to delete it: cinder delete 0f70ccb6-85ba-4726-bda8-4051b68e943e Delete for volume 0f70ccb6-85ba-4726-bda8-4051b68e943e failed: Internal Server Error (HTTP 500) ERROR: Unable to delete any of the specified volumes. cinder delete 239bab9d-a70c-470e-ad13-9100946d8ca7 Delete for volume 239bab9d-a70c-470e-ad13-9100946d8ca7 failed: Internal Server Error (HTTP 500) ERROR: Unable to delete any of the specified volumes. The consistency of the two volumes isn't ensured anymore and my two volumes are unusable at the OpenStack level. So, in a word, my point is, how do you manage LVM volumes migration between your Cinders and how do you upgrade OpenStack Cinder nodes with used volumes on it ? Any help would be great, Thanks
