DESCRIPTION

84       ceph-disk is a utility that can prepare and activate a disk,  partition
85       or  directory  as  a  Ceph  OSD.  It  is  run  directly or triggered by
86       ceph-deploy or udev. It can also be triggered by other deployment util‐
87       ities like Chef, Juju, Puppet etc.
88
89       It  actually  automates  the multiple steps involved in manual creation
90       and start of an OSD into two steps of preparing and activating the  OSD
91       by using the subcommands prepare and activate.
92
93       ceph-disk  also  automates the multiple steps involved to manually stop
94       and destroy an OSD into two steps of deactivating  and  destroying  the
95       OSD by using the subcommands deactivate and destroy.
96
97       The  documentation for each subcommand (prepare, activate, etc.) can be
98       displayed with  its  --help  option.  For  instance  ceph-disk  prepare
99       --help.
