Fixed In Version: ceph-16.2.8-65.el8cp
Doc Type: Bug Fix
Doc Text:
.`last_copied_object_number` value is properly updated for all images Previously, due to an implementation defect, `last_copied_object_number` value was properly updated only for fully allocated images. This caused the `last_copied_object_number` value to be incorrect for any sparse image and the image replication progress to be lost in case of abrupt rbd-mirror daemon restart. With this fix, `last_copied_object_number` value is properly updated for all images and upon rbd-mirror daemon restart, image replication resumes from where it had previously stopped.

How reproducible:
Tried once, Will try further

Steps to Reproduce:

2. configure rbd mirroring with another cluster
3. enable snapshot based mirroring on the image
4. Observe the mirror image status

Actual results:
syncing_percent gets stuck at 4 throughout the sync (observed from 1 to 4)

Expected results:
