I want to do some test in container with ceph,
but after i install ceph, i find osd doesn't be installed
successfully:
[root@f3c3a6580a0f ~]$ ceph -s

I only found below error from install log:
Traceback (most recent call last):

rdev = os.stat(path).st_rdev
OSError: [Errno 2] No such file or directory: '/dev/dm-6'
but next info confused me:
[ceph_deploy.osd][DEBUG ] Host 172.17.0.4 is now ready for osd use.
In 172.17.0.4, `ceph-disk list` show above error too.
Since start container in order, i can call `ceph-disk list` in the last
one without above error.
I know ceph-deploy would call ceph-disk, but above error do not make
whole install process exit and in docker, the dm type device is for
containers self. Is there any possible to skip dm device and make ceph
install osd succeed indeed?
