Hi all,
--
We setup rbd mirroring between 2 clusters, but have issues when we want to delete one image. Following is the detailed info.
It reports that some other instance is still using it, which kind of makes sense because we set up the mirror between 2 clusters.
What's the best practice to remove a image which is under rbd mirroring?
By the way, we did a pool based rbd mirroring.
rbd --cluster iad rm <image name> -p mirror
2016-10-19 15:46:44.843053 7f35c9925d80 -1 librbd: cannot obtain exclusive lock - not removing
Removing image: 0% complete...failed.
rbd: error: image still has watchers
This means the image is still open or the client using it crashed. Try again after closing/unmapping it or waiting 30s for the crashed client to timeout.
Think big; Dream impossible; Make it happen.
