NAME

6       mkcephfs - create a ceph file system
7

SYNOPSIS

9       mkcephfs [ -a ] [ -c ceph.conf ] [ --clobber_old_data ] [ --mkbtrfs ]
10

DESCRIPTION

12       mkcephfs is used to create an empty Ceph file system, possibly spanning
13       multiple hosts.  The ceph.conf file describes the  composition  of  the
14       Ceph  cluster,  including  which hosts are participating, which daemons
15       run where, and which paths are used to store file system data or  meta‐
16       data.
17

OPTIONS

19       -a, --allhosts
20              Performs  the necessary initialization steps on all hosts in the
21              cluster, executing commands via SSH.
22
23       -c ceph.conf, --conf=ceph.conf
24              Use   the   given   conf   file   instead   of    the    default
25              /etc/ceph/ceph.conf.
26
27       --clobber_old_data
28              Overwrite any existing data found in monitor or osd paths.
29
30       --mkbtrfs
31              Create  and  mount  the  any btrfs file systems specified in the
32              ceph.conf for OSD data storage  using  mkfs.btrfs.   The  "btrfs
33              devs"  and  (if it differs from "osd data") "btrfs path" options
34              must be defined.
35
