Hi Liuchang0812,
Thank you for replying the thread.
I have corrected this issue. This was due to incorrect ownership of the
/var/lib/ceph. It was under root and I have changed it to ceph ownership
to resolve this.
However, I am seeing a new error while preparing the osd's. Any idea
about this?

Hi, Vince
What's your Ceph's version ?

Hi,
We are getting the below error while trying to create monitor from the admin

I couldn't see /var/run/ceph/ceph-mon.osd-ceph1.aso in the monitor server.
