Hi, I am deploying a 3 node ceph storagollowing thee cluster for my company, following the webinar: http://www.youtube.com/watch?v=R3gnLrsZSno I am stuck at formating the osd's and making them ready to mount the directories. Below is the error thrown back: root@ceph-node1:~# mkcephfs -a -c /etc/ceph/ceph.conf -k ceph.keyring --mkfs unrecognized option '--mkfs' usage: /sbin/mkcephfs -a -c ceph.conf [-k adminkeyring] [--mkbtrfs] to generate a new ceph cluster on all nodes; for advanced usage see man page ** be careful, this WILL clobber old data; check your ceph.conf carefully ** Changing the --mkfs flag to --mkbtrfs results in the error below: root@ceph-node1:~# mkcephfs -a -c /etc/ceph/ceph.conf -k ceph.keyring --mkbtrfs temp dir is /tmp/mkcephfs.By7pV0aY0W preparing monmap in /tmp/mkcephfs.By7pV0aY0W/monmap /usr/bin/monmaptool --create --clobber --add a 192.168.56.21:6789 --add b 192.168.56.22:6789 --add c 192.168.56.23:6789 --print /tmp/mkcephfs.By7pV0aY0W/monmap /usr/bin/monmaptool: monmap file /tmp/mkcephfs.By7pV0aY0W/monmap /usr/bin/monmaptool: generated fsid de3258d8-1a1f-427d-91ca-cbc679f75305 epoch 0 fsid de3258d8-1a1f-427d-91ca-cbc679f75305 last_changed 2014-10-15 09:35:41.950988 created 2014-10-15 09:35:41.950988 0: 192.168.56.21:6789/0 mon.a 1: 192.168.56.22:6789/0 mon.b 2: 192.168.56.23:6789/0 mon.c /usr/bin/monmaptool: writing epoch 0 to /tmp/mkcephfs.By7pV0aY0W/monmap (3 monitors) === osd.0 === no btrfs devs defined for osd.0 2014-10-15 09:35:42.183383 7f9a06bca780 must specify '--osd-data="" data path 2014-10-15 09:35:42.192312 7f9a06bca780 usage: ceph-osd -i osdid [--osd-data="" [--osd-journal=path] [--mkfs] [--mkjournal] [--convert-filestore] 2014-10-15 09:35:42.192602 7f9a06bca780 --debug_osd N set debug level (e.g. 10) --conf/-c Read configuration from the given configuration file -d Run in foreground, log to stderr. -f Run in foreground, log to usual location. --id/-i set ID portion of my name --name/-n set name (TYPE.ID) --version show version and quit --debug_ms N set message debug level (e.g. 1) failed: '/sbin/mkcephfs -d /tmp/mkcephfs.By7pV0aY0W --init-daemon osd.0' Please help Regards, Sakhi Hadebe Engineer: South African National Research Network (SANReN)Competency Area, Meraka, CSIR Tel: +27 12 841 2308 Fax: +27 12 841 4223 Cell: +27 71 331 9622 Email: shadebe@xxxxxxxxxx -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.
