7
9 mkcephfs [ -a ] [ -c ceph.conf ] [ --clobber_old_data ] [ --mkbtrfs ]
10
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
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
37 mkcephfs is part of the Ceph distributed file system. Please refer to
38 the Ceph wiki at http://ceph.newdream.net/wiki for more information.
