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.
