Hello,

All sources saying that ceph provides data for VMs via public_network. Also in fuel panel I can see "The Storage network is used to provide storage services such as replication traffic from Ceph. The Management network is used for Ceph Public traffic."

But in my deployment ceph public traffic going thru storage network. I dont know why fuel deployed it this way. Could anyone explain it for me? I would be grateful.

Storage: 209.0.113.0/24, VLAN 102

Management: 207.0.113.0/24, VLAN 101
