Proxmox VE 3.2 HA cluster with multiple nics

[Christophe Aubry]

Hi,

We currently testing a Proxmox VE 3.2 HA-Cluster composed of 3 nodes with Ceph as storage, each node have a 10Gbe network for the data and administration tasks, there is also an 1Gbe network for the virtual machines. When we unplug the 10Gbe network of one of the node the node is being fenced and all the virtual machines are migrate to another node bu when we disconnecting the 1Gbe network nothing happens and all the virtual machines on that node lost their network connection.
There is the possibilities to add another nic to the HA configuration ?

Use bonding. See-> http://www.youtube.com/watch?v=-8SwpgaxFuk

We already using ethernet bonding on each network but what we want to reproduce is the setup we have with our ESX 3.5 cluster, in this setup the VM are mapped to some dedicated interfaces on a LAN an a DMZ network that didn't have IP address to avoid hacker to connect to the ESX from Internet, the data and management network are mapped to another interface only accessible from our office network.
The only thing i found is to use a parameter called "altname" into the cluster.conf but with this option i need to use an IP on the dedicated VM interface and the other problem is that all the interfaces need to be down to fence the host and move the VM, on our ESX cluster when the dedicated VM interface going down all the VM are moved to another host no matter if other network are up or not.
