Hi guys, when creating an rbd with feature "exclusive-lock" (and object-map, fast-diff, ..), do I have to pass any special arguments to qemu to activate it?
How does this feature work with resize, snapshot creation, etc.? Form my work on ceph-ruby I know you have to call "rbd_open" and then pass the returned handle to "rbd_resize", "rbd_snap_create" etc. However with "exclusive-lock" I assume rbd_open will fail (does it?) if it's currently used by for example a qemu client. So there's no way to create snapshots while the image is in use? Or do I miss anything here?
