Hi, has it worked for any other glance image? The snapshot shouldn't make any difference, I just tried the same in a lab cluster. Have you checked on the client side (OpenStack) for anything in dmesg etc.? Can you query any information from that image? For example: rbd info images_meta/image_name rbd status images_meta/image_name Is the Ceph cluster healthy? Maybe you have inactive PGs on the glance pool?

Hi everyone.

I am trying Image Live-Migration but it is not working well and I would like some advice. https://docs.ceph.com/en/latest/rbd/rbd-live-migration/

I use Ceph as a backend for OpenStack Glance. I tried to migrate the Pool of Ceph used in Glance to the new Pool.

Source Pool: - images_meta : metadata pool, Replication - images_data : data pool, Erasure Code Target Pool: - images_meta: metadata pool, Replication (Same as source Pool) - images_data_hdd: data pool, Erasure Code

The following command I executed, but did not return a response.

rbd migration prepare images_meta/image_name images_meta/image_name --data-pool images_data_hdd

I checked the logs in /var/log/messages and /var/log/ceph, but no useful information was available. I would like some advice on this. - Are there any other logs I should check? - Is there a case where the rbd migration command cannot be executed?

The following is supplemental information. - ceph version 17.2.8 - The migration of the OpenStack Nova image was successful with the same Pool configuration and command. - I don't know if it is related, but there is a snapshot in the image of Glance, and unprotect of the snapshot is also unresponsive. rbd snap unprotect images_meta/image_name@snap _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
