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 [ceph_deploy.mon][DEBUG ] detecting platform for host web2 ...

Looks like I mis-configured the network environment?
