NAME

       mkcephfs - create a ceph file system

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

       -a, --allhosts
              Performs  the necessary initialization steps on all hosts in the
              cluster, executing commands via SSH.

       -c ceph.conf, --conf=ceph.conf
              Use   the   given   conf   file   instead   of    the    default
              /etc/ceph/ceph.conf.

       --clobber_old_data
              Overwrite any existing data found in monitor or osd paths.

       --mkbtrfs
              Create  and  mount  the  any btrfs file systems specified in the
              ceph.conf for OSD data storage  using  mkfs.btrfs.   The  "btrfs
              devs"  and  (if it differs from "osd data") "btrfs path" options
              must be defined.

AVAILABILITY

       mkcephfs is part of the Ceph distributed file system.  Please refer  to
       the Ceph wiki at http://ceph.newdream.net/wiki for more information.
