This document is for a development version of Ceph.


The inventory subcommand queries a host’s disc inventory and provides hardware information and metadata on every physical device.

By default the command returns a short, human-readable report of all physical disks.

For programmatic consumption of this report pass --format json to generate a JSON formatted report. This report includes extensive information on the physical drives such as disk metadata (like model and size), logical volumes and whether they are used by ceph, and if the disk is usable by ceph and reasons why not.

A device path can be specified to report extensive information on a device in both plain and json format.
