Hello, I've been playing with backing up images from my production site (running 0.87) to my backup site (running 0.87.1) using export/import and export-diff/import-diff. After initially exporting and importing the image (rbd/small to backup/small) I took a snapshot (called test1) on the production cluster, ran export-diff from that snapshot, and then attempted to import-diff the diff file on the backup cluster.
# rbd import-diff ./foo.diff backup/small start snapshot 'test1' does not exist in the image, aborting Importing image diff: 0% complete...failed. rbd: import-diff failed: (22) Invalid argument This works fine if I create a test1 snapshot on the backup cluster before running import-diff. However, it appears that the changes get written into backup/small not backup/small@test1. So unless I'm not understanding something, it seems like the content of the snapshot on the backup cluster is of no importance, which makes me wonder why it must exist at all. Any thoughts?
