Hi all,

I’m not really sure what the topic should be called.
I just finished setting up a new set of servers that have the following 
configuration

Nodes 1 and 2 Public Network: 172.16.10.12 & 172.16.10.13
Nodes 1 and 2 Private Network: 10.1.1.12 & 10.1.1.13
Back end NFS / iSCSI Storage: 10.1.1.3

The back end is comprised of 10GB Ethernet, which is why I want to utilize 
this. 
I can mount the NFS share on the 10.1.1.0/24 range without any issue on the 
servers and I can restore a VM (Win2012) and can migrate from one node to 
another without any issue.

I then setup each server to have a 300GB iSCSI partition and I’ve replaced the 
existing /var/lib/vz partition with the iSCSI partition and it mounts without 
issue every time.

I then restored an openVZ container to the iSCSI volume mounted at /var/lib/vz 
and it works perfectly fine. My issue that I’m having is when I try to migrate 
the guest open VZ from one node to the other, it wants to copy it over the 
172.16.10.0/24 network, which is link agg for 2GB connectivity, but I’d rather 
have it copy the data over the 10.1.1.0/24 network since its a dedicated 
private 10GB network, and in theory much faster.

When I setup the server, I gave the servers vmbr0 the 172.16.0.12 and 
172.16.10.13 network IPs. I then created a bond and actually swapped them 
around so now the setup for both servers is as follows:

vmbr0 - 10.1.1.0 network range - Bridge for eth3 which is a 10GB port
vmbr1 - 172.16.10.0 network range - Bond for eth0 / eth1 which is on a 2GB 
802.ad link agg

When I built the cluster for the servers I built it on the 10.1.1.0/24 range so 
I believe thats done properly.

I guess my question is: What do I have to do in order to get the servers within 
the cluster to migrate / copy the data from the one iSCSI volume to the other 
over the 10.1.1.0 network and not over the slower public network?

Thanks for any help.
