Description¶
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.
