Bridge to Bond?

[longhair]

I need to have a Windows VM connect to the nfs server. After adding a 2nd nic and giving it a static ip address using the 192.168.2.x subnet, I realized it wouldn't work because the bridge is for the 192.168.1.x subnet.

How would I create a new bridge to the existing bond without losing access to the nfs server (all running VMs are on there).

bond0 is proxmox <-> nfs server.

# network interface settings
auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

iface eth2 inet manual

iface eth3 inet manual

auto bond0
iface bond0 inet static
        address  192.168.2.100
        netmask  255.255.255.0
        slaves eth1 eth2
        bond_miimon 100
        bond_mode 802.3ad

auto vmbr0
iface vmbr0 inet static
        address  192.168.1.100
        netmask  255.255.255.0
        gateway  192.168.1.1
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0

You could create a bridge using a different vlan like:

auto vmbr10
iface vmbr10 inet manual
bridge_ports bond0.10
bridge_stp off
bridge_fd 0

This will create bridge using vlan 10 over the original bridge0. However, it requires a vlan enabled switch. Connection to this bridge most obviously use a different net than 192.168.2.0/24

BTW. you should not configure ip and network on the bond.

Are you sure? You want to access the nfs server from inside the VM, so adding IP on the host makes no sense to me.

Since I am unable to keep an external USB drive from sleeping, I need to make a directory on the nfs for a Windows VM to access.

In the past I've added a hard disk from the web console and mapped that to the nfs but the data didn't survive a removal & creation of a new VM.

I set up the bond following the Bond Configuration with Proxmox VE video
