I've change the /etc/pve/ceph.conf , in the begining the are in the same network 10.0.141.x/24, now I change ceph cluster to 10.98.141.0/24



Code: 
[global]
     auth_client_required = cephx
     auth_cluster_required = cephx
     auth_service_required = cephx
     cluster_network = 10.98.141.0/24
     fsid = 2c475bdb-82b2-4614-ad15-becbd73c6c68
     mon_allow_pool_delete = true
     mon_host = 10.0.141.1 10.0.141.4 10.0.141.3 10.0.141.2 10.0.141.5 10.0.141.6 10.0.141.7
     osd_pool_default_min_size = 2
     osd_pool_default_size = 2
     public_network = 10.0.141.0/16


Then I run this command to restart ceph, to make it work.

Code: 
systemctl restart ceph.target



Then I found that osd still listening both public & cluster network, is this ok? If they work together, I'm afraid the net flow still in the old public network.

Code: 
root@g8kvm01:~# netstat -nap | grep ceph-osd | more

Hi,
The OSD must listen to both networks. Only the replication traffic uses the private network.
