Hi there, We are replicating a RBD image from Primary to DR site using RBD mirroring. On Primary, we were using 10.2.10. DR site is luminous and we promoted the DR copy to test the failure. Everything checked out good. Now we are trying to restart the replication and we did the demote and then resync the image but it stuck in “starting_replay” state for last 3 days. It’s a 200TB RBD image :~# rbd --cluster cephdr mirror pool status nfs --verbose health: WARNING images: 1 total 1 starting_replay dir_research: global_id: 3ad67d0c-e06b-406a-9469-4e5faedd09a4 state: down+unknown description: status not found last_update: #rbd info nfs/dir_research rbd image 'dir_research': size 200TiB in 52428800 objects order 22 (4MiB objects) block_name_prefix: rbd_data.652186b8b4567 format: 2 features: layering, exclusive-lock, journaling flags: create_timestamp: Thu Feb 7 11:53:36 2019 journal: 652186b8b4567 mirroring state: disabling mirroring global id: 3ad67d0c-e06b-406a-9469-4e5faedd09a4 mirroring primary: false So the question is, how do we know the progress of the replay and how much its already completed and any ETA estimation on when it will go back to OK state? Thanks, -Vikas |
