Hi,
I've setup a ceph cluster using cephadmin on three ubuntu servers. Everything went great until I tried to activate a osd prepared on a lvm.
I have prepared 4 volumes with the command:
ceph-volume lvm prepare --data vg/lv
Now I try to activate one of them with the command (followed by the output):
root@hvs001:/# ceph-volume lvm activate 0 25bfe96a-4f7a-47e1-8644-b74a4d104dbc
Running command: /usr/bin/mount -t tmpfs tmpfs /var/lib/ceph/osd/ceph-0
Running command: /usr/bin/chown -R ceph:ceph /var/lib/ceph/osd/ceph-0
Running command: /usr/bin/ceph-bluestore-tool --cluster=ceph prime-osd-dir --dev /dev/hvs001_sda2/lvol0 --path /var/lib/ceph/osd/ceph-0 --no-mon-config
Running command: /usr/bin/ln -snf /dev/hvs001_sda2/lvol0 /var/lib/ceph/osd/ceph-0/block
Running command: /usr/bin/chown -h ceph:ceph /var/lib/ceph/osd/ceph-0/block
Running command: /usr/bin/chown -R ceph:ceph /dev/dm-1
Running command: /usr/bin/chown -R ceph:ceph /var/lib/ceph/osd/ceph-0
Running command: /usr/bin/systemctl enable ceph-volume@lvm-0-25bfe96a-4f7a-47e1-8644-b74a4d104dbc
stderr: Created symlink /etc/systemd/system/multi-user.target.wants/ceph-volume@lvm-0-25bfe96a-4f7a-47e1-8644-b74a4d104dbc.service -> /usr/lib/systemd/system/ceph-volume@.service.
Running command: /usr/bin/systemctl enable --runtime ceph-osd@0
stderr: Created symlink /run/systemd/system/ceph-osd.target.wants/ceph-osd@0.service -> /usr/lib/systemd/system/ceph-osd@.service.
Running command: /usr/bin/systemctl start ceph-osd@0
stderr: Failed to connect to bus: No such file or directory
--> RuntimeError: command returned non-zero exit status: 1
Seems systemd isn't playing along?
Please advice.
Some additional backround info:
