Doc Text:	.Set the `syncing_percent` value to `0` Previously, when an image snapshot copy was interrupted and restarted, the `rbd-mirror` would not have details of the last object copied for that image. The `syncing_percent` calculation, which relies on this information, returned an invalid percentage value. With this fix, if the information about the last object is unavailable, you can set the `syncing_percent` to `0` until the last object copied is updated.	Story Points:	---

Description Vasishta 2022-07-12 16:32:50 UTC

Description of problem:
1) created two clusters, created 26 images both the sides, ran some IOs
Created 76 more images on one of the sites (site-a)

2) Observed that one of the non-primary image at site-a snapshot schedule stuck - Could be because of BZ 2102061

3) All secondary images in site-a were reported error - BZ 2105308

4) site-b had laggy osds and some undersized pgs by 1 replica. Scaled up and uppgraded twice to latest build of rhcs 5.2 (just 2-3 builds ahead).

5) all error ful reports in site-a were gone.

6) the observed secondary snapshot creation (as mentioned in above point 2) was still stuck.
Tried restarting of mgr as a workaround. Did not work.

**Tried image resync**

Then observed that syncing_percent in description part of rbd mirror image status was stuck at 3072000
