@ -458,49 +439,48 @@ Remove a Ceph OSD device with ID `<osd>` from the storage cluster.
**NOTE:** This is a command with potentially dangerous unintended consequences that should not be scripted. To acknowledge the danger, the `yes_i_really_mean_it` must be set or the endpoint will return a failure.
**WARNING:** Removing an OSD without first setting it `out` (and letting it flush) triggers an unclean PG recovery. This could potentially cause data loss if other OSDs were to fail or be removed. OSDs should not normally be removed except in the case of failed OSDs during replacement or during a replacement with a larger disk.

If `limit` is specified, return a JSON document containing information about all Ceph RBD volume snapshots with names matching `limit` as fuzzy regex.
The various limit options can be combined freely, e.g. one can specify a `volume` without `pool`, which would match all snapshots of the named volume(s) regardless of pool, or a `pool` and `limit` without a `volume`, which would match all named snapshots on any volume in `pool`.
