ceph-disk is a utility that can prepare and activate a disk, partition or directory as a Ceph OSD. It is run directly or triggered by ceph-deploy or udev. It can also be triggered by other deployment utilities like Chef, Juju, Puppet etc. It actually automates the multiple steps involved in manual creation and start of an OSD into two steps of preparing and activating the OSD by using the subcommands prepare and activate. ceph-disk also automates the multiple steps involved to manually stop and destroy an OSD into two steps of deactivating and destroying the OSD by using the subcommands deactivate and destroy. The documentation for each subcommand (prepare, activate, etc.) can be displayed with its --help option. For instance ceph-disk prepare --help.

ceph-disk is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the Ceph documentation at for more information.
