Code review comment for lp:~seyeongkim/charms/trusty/ceph/lp1411652

Hello. I tested only charms over openstack env and maas with one lxc for one unit.
There was no special problem. but after you comment. I think there could be a problem in case that one machine for multiple unit.
I haven't check this case yet. will do in this week and modify code if there is something.
Thanks.
