Hello Cary！
It’s really big surprise for me to receive your reply！
Sincere thanks to you！
I know it’s a fake execute file, but it works!
====================>
$ cat /usr/sbin/systemctl
#!/bin/bash
exit 0
<====================
I can start my osd by following command
/usr/bin/ceph-osd --cluster=ceph -i 12 -f --setuser ceph --setgroup ceph
But, threre are still problems.
1.Though ceph-osd can start successfully, prepare log and activate log looks
like errors occurred.
Prepare log:
=======================================>

<=======================================
Activate log:
=======================================>
# ceph-volume lvm activate --bluestore 12 827f4a2c-8c1b-427b-bd6c-66d31a0468ac
Running command: sudo ceph-bluestore-tool --cluster=ceph prime-osd-dir --dev
/dev/vggroup/lv --path /var/lib/ceph/osd/ceph-12
Running command: sudo ln -snf /dev/vggroup/lv /var/lib/ceph/osd/ceph-12/block
Running command: chown -R ceph:ceph /dev/dm-0
Running command: chown -R ceph:ceph /var/lib/ceph/osd/ceph-12
Running command: sudo systemctl enable
ceph-volume@lvm-12-827f4a2c-8c1b-427b-bd6c-66d31a0468ac
Running command: sudo systemctl start ceph-osd@12
<=======================================
After activate operation , osd did not start , but I can start osd by the
following command(before restart host)
/usr/bin/ceph-osd --cluster=ceph -i 12 -f --setuser ceph --setgroup ceph
2. After host reboot, everything about ceph-osd has been lost.
Because before I reboot, /var/lib/ceph/osd/ceph-12 was mounted on tmpfs, so
after reboot I lost everything about ceph-osd.
#df -h
/dev/root 15G 2.4G 12G 18% /
devtmpfs 1009M 4.0K 1009M 1% /dev
none 4.0K 0 4.0K 0% /sys/fs/cgroup
none 202M 156K 202M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 1009M 0 1009M 0% /run/shm
none 100M 0 100M 0% /run/user
tmpfs 1009M 48K 1009M 1% /var/lib/ceph/osd/ceph-12
3. ceph-osd can not start automatically.
I think there are something wrong in osd upstart, I should add some operation
about osd upstart.
It seems that this ceph-volume for ubuntu14.04 is not a easy problem for me ,
so any suggestions or hints about the problems will be appreciated!
