bond0 failed when set as bridge_ports

[Paulo Maligaya]

Hi, I have a server that has already a bonded interface configured prior on Proxmox installation. Right now, I'm trying to setup a bridge interface vmbr0 in particular, but everytime I set the bridge_ports to bond0 my main network failed and I can no longer connect to the main host/node (as if the connectivity went down). Here's the entire look of my /etc/network/interfaces:

-----
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 147.x.x.x
netmask 255.x.x.x
gateway 147.x.x.x
slaves none
bond_miimon 100
bond_mode balance-rr
bond-slaves eth2 eth3
dns-nameservers 8.8.8.8 8.8.4.4
bond-xmit_hash_policy layer3+4
bond-downdelay 200
bond-updelay 200
bond-miimon 100
bond-mode 4

iface bond0 inet6 static
address 1111:2222:3:c444::55
netmask 127
gateway 1111:2222:3:c444::54

auto bond0:0
iface bond0:0 inet static
address 10.x.x.x
netmask 255.x.x.x
post-up route add -net 10.0.0.0/8 gw 10.x.x.x
post-down route del -net 10.0.0.0/8 gw 10.x.x.x

auto vmbr0
iface vmbr0 inet static
address 198.x.x.x
netmask 255.x.x.x
bridge_ports bond0
bridge_stp off
bridge_fd 0
bridge_vlan_aware yes
-----

And my bridge (vmbr0) is already linked to bond0

# brctl show
bridge name bridge id STP enabled interfaces
vmbr0 8000.f45214702e70 no bond0


Anyone already experienced this issue?

TIA!

I think ( not sure here, please someone correct) that the problem here is that if you configure bond0 as a port of vmbr0, you should configure do the IP configuration on vmbr0, not bond0.

So try to move the IP configuration from bond0 to vmbr0, and configure your IP alias bond0:0 on vmbr0 as a post-up
