Description Jason Dillaman 2017-05-04 09:43:42 EDT

Description of problem:
After a forced-failover event from site A to site B, if you delete the image on site A (while it's still primary) via "rbd rm <image-spec>", rbd-mirror will correctly detect that it should replicate the image from site B back to site A. Unfortunately, it skips the actual image sync step and just creates an empty image.

Restarting the rbd-mirror daemon on site A or requesting a manual resync will correct the issue.

Version-Release number of selected component (if applicable):
10.2.x

How reproducible:
100%

Steps to Reproduce:
1. rbd --cluster siteB mirror image promote --force <image-spec>
2. rbd --cluster siteA rm <image-spec>

Actual results:
A blank (zeroed) image will be re-created on siteA

Expected results:
A properly synchronized image will be re-created on siteA
