Hi, I'm following the Manual Deployment guide at http://docs.ceph.com/docs/ master/install/manual-deployment/ I'm not able to move past the ceph-volume lvm create part. Here is what I do:
# lvcreate -L 1G -n ceph cah_foo Logical volume "ceph" created. # ceph-volume lvm create --data cah_foo/ceph Running command: /bin/ceph-authtool --gen-print-key Running command: /bin/ceph --cluster ceph --name client.bootstrap-osd --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring -i - osd new b8016385-e46c-4e93-a334-be4fc92bea85 Running command: /bin/ceph-authtool --gen-print-key Running command: mount -t tmpfs tmpfs /var/lib/ceph/osd/ceph-0 Running command: chown -R ceph:ceph /dev/dm-2 Running command: ln -s /dev/cah_foo/ceph /var/lib/ceph/osd/ceph-0/block Running command: ceph --cluster ceph --name client.bootstrap-osd --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring mon getmap -o /var/lib/ceph/osd/ceph-0/activate.monmap stderr: got monmap epoch 2 Running command: ceph-authtool /var/lib/ceph/osd/ceph-0/keyring --create-keyring --name osd.0 --add-key AQCxuhlbAVylMRAAXsKQpKbau3T1rI 66z651ng== stdout: creating /var/lib/ceph/osd/ceph-0/keyring added entity osd.0 auth auth(auid = 18446744073709551615 key= AQCxuhlbAVylMRAAXsKQpKbau3T1rI66z651ng== with 0 caps) Running command: chown -R ceph:ceph /var/lib/ceph/osd/ceph-0/keyring Running command: chown -R ceph:ceph /var/lib/ceph/osd/ceph-0/ Running command: /bin/ceph-osd --cluster ceph --osd-objectstore bluestore --mkfs -i 0 --monmap /var/lib/ceph/osd/ceph-0/activate.monmap --keyfile - --osd-data /var/lib/ceph/osd/ceph-0/ --osd-uuid b8016385-e46c-4e93-a334-be4fc92bea85 --setuser ceph --setgroup ceph stderr: 2018-06-07 16:07:32.804440 7f237709dd80 -1 bluestore(/var/lib/ceph/osd/ceph-0/) _read_fsid unparsable uuid stderr: 2018-06-07 16:07:33.822761 7f237709dd80 -1 OSD::mkfs: ObjectStore::mkfs failed with error (2) No such file or directory stderr: 2018-06-07 16:07:33.822934 7f237709dd80 -1 *** ERROR: error creating empty object store in /var/lib/ceph/osd/ceph-0/: (2) No such file or directory* --> ceph-volume lvm prepare successful for: cah_foo/ceph Running command: ceph-bluestore-tool --cluster=ceph prime-osd-dir --dev /dev/cah_foo/ceph --path /var/lib/ceph/osd/ceph-0 stderr: failed to read label for /dev/cah_foo/ceph: (2) No such file or directory --> Was unable to complete a new OSD, will rollback changes --> OSD will be fully purged from the cluster, because the ID was generated Running command: ceph osd purge osd.0 --yes-i-really-mean-it stderr: purged osd.0 --> RuntimeError: command returned non-zero exit status: 1 # ceph --version ceph version 12.2.5 (cad919881333ac92274171586c827e01f554a70a) luminous (stable) I wonder what am I missing and what else I can try.
