Hi ceph-users,
I deployed a cluster successfully in VMs, and today I tried to deploy a cluster
in physical nodes. However, I came across a problem when I started creating a
monitor.
-bash-4.1$ ceph-deploy mon create xxxxx
[ceph_deploy.mon][DEBUG ] Deploying mon, cluster ceph hosts xxxxxxxx

Does anyone come across the same issue? Looks like I mis-configured the network
environment?
Thanks,
Guang
