Bug #57902
Updated by Ilya Dryomov over 1 year ago
As any snapshot in a non-user snapshot namespace, mirror snapshots are inaccessible to most rbd CLI commands. As such, inspecting mirror snapshot contents is much harder than it should be -- they can't be diffed, exported, etc. Let's allow them to be mapped at least. <pre> $ sudo rbd device map -t nbd --snap-id 123 -o snap_id=123 testpool/testimage /dev/nbd0 </pre>
