I am trying to get Ceph running on an ARM system, currently one quad core node, running Ubuntu 12.04. It compiles fine, currently without tcmalloc and google perf tools, but I am running into a problem with mkcephfs. 'mkcephfs -a -c ceph.conf' didn't work so I did it piece by piece until I got this: root@ubuntu:/home/tim# mkcephfs -d /tmp/foo --prepare-mon Building generic osdmap from /tmp/foo/conf /usr/local/bin/osdmaptool: osdmap file '/tmp/foo/osdmap' /usr/local/bin/osdmaptool: writing epoch 1 to /tmp/foo/osdmap Generating admin key at /tmp/foo/keyring.admin creating /tmp/foo/keyring.admin Building initial monitor keyring cat: /tmp/foo/key.*: No such file or directory There are no key.* files in /tmp/foo # ls /tmp/foo conf keyring.admin keyring.mon monmap osdmap If you are running everything on one node, is it OK to use localhost and 127.0.0.1? Here is my config file: [osd] osd journal size = 1000 filestore xattr use omap = true [mon.a] host = localhost mon addr = 127.0.0.1:6789 [osd.0] host = localhost [mds.a] host = localhost Here are are the other configuration commands: root@ubuntu:/home/tim# mkcephfs -c ceph.conf -d /tmp/foo --prepare-monmap preparing monmap in /tmp/foo/monmap /usr/local/bin/monmaptool --create --clobber --add a 127.0.0.1:6789 --print /tmp/foo/monmap /usr/local/bin/monmaptool: monmap file /tmp/foo/monmap /usr/local/bin/monmaptool: generated fsid 8e4f846b-1829-46e4-9902-5d8316c3fa4f epoch 0 fsid 8e4f846b-1829-46e4-9902-5d8316c3fa4f last_changed 2012-07-19 22:40:38.651045 created 2012-07-19 22:40:38.651045 0: 127.0.0.1:6789/0 mon.a /usr/local/bin/monmaptool: writing epoch 0 to /tmp/foo/monmap (1 monitors) root@ubuntu:/home/tim# mkcephfs -d /tmp/foo --init-local-daemons mds root@ubuntu:/home/tim# mkcephfs -d /tmp/foo --init-local-daemons osd root@ubuntu:/home/tim# mkcephfs -d /tmp/foo --prepare-mon Building generic osdmap from /tmp/foo/conf /usr/local/bin/osdmaptool: osdmap file '/tmp/foo/osdmap' /usr/local/bin/osdmaptool: writing epoch 1 to /tmp/foo/osdmap Generating admin key at /tmp/foo/keyring.admin creating /tmp/foo/keyring.admin Building initial monitor keyring cat: /tmp/foo/key.*: No such file or directory root@ubuntu:/home/tim# Any ideas?
