My guess is a networking problem. Do you have vlans, cluster network vs
public network in the ceph.conf, etc configured? Can you ping between all
of your storage nodes on all of their IPs?
All of your OSDs communicate with the mons on the public network, but they
communicate with each other for peering on the cluster network. My guess
is that your public network is working fine, but that your cluster network
might be having an issue causing the new PGs to never be able to peer.
