Description

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.

$ sudo rbd device map -t nbd --snap-id 123 testpool/testimage
/dev/nbd0
