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
images: 1 total
description: status not found
#rbd info nfs/dir_research
rbd image 'dir_research':
size 200TiB in 52428800 objects
order 22 (4MiB objects)
features: layering, exclusive-lock, journaling
create_timestamp: Thu Feb 7 11:53:36 2019
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
