Hi!
I am trying to install ceph in container, but osd always failed:
[root@d32f3a7b6eb8 ~]$ ceph -s
cluster:
id: a5f1d744-35eb-4e1b-a7c7-cb9871ec559d
health: HEALTH_WARN
Reduced data availability: 128 pgs inactive
Degraded data redundancy: 128 pgs unclean

mgr: d32f3a7b6eb8(active), standbys: 1d22f2d81028
mds: cephfs-1/1/1 up {0=1d22f2d81028=up:creating}, 1 up:standby
osd: 0 osds: 0 up, 0 in
data:
pools: 2 pools, 128 pgs
objects: 0 objects, 0 bytes
usage: 0 kB used, 0 kB / 0 kB avail
pgs: 100.000% pgs unknown
128 unknown
Since docker can not create and access new partition, i create
partition at host then use --device to make it available in container.
>From the install log, i only found below error:
Traceback (most recent call last):

rdev = os.stat(path).st_rdev
OSError: [Errno 2] No such file or directory: '/dev/dm-6'
But it didn't make whole install exit. I enter container and call
`ceph-disk list` then same error occur.
I know that create osd need to call `ceph-disk`, while dm device is
for container storage, it would be better if `ceph-disk` can skip dm
device.
I guess this error lead osd create fail since i do not get other error
info.
