static LAG not working

Hi there,

For a while now I've been using Proxmox, and before that ESXi. I've got everything connected to a pair of Dell powerconnect 2824's, which only support static LAG.
That worked fine on ESXi, but when using Proxmox I've got connectivity issues. One part of the devices in the networks cant reach other devices, where others don't have problems at all.
I'm using intel pro1000 dual nics, and a somewhat recent version of proxmox (patched to a point of around 30 days ago).
I couldn't figure this one out on my own. The workaround is to just don't use the two interfaces of the dual NIC, but since the hardware is capable of static LAG, I'd like to be able to use it. Especially since the single gigabit interface is limiting the throughput often, when one VM/service decides to push a lot over the network.
The NAS, using the same NIC but runs FreeNAS, and has got no issues with network connectivity when I switch the cables an run the NAS on the LAG of ths proxmox server.
So.. does anyone have a idea on how do I fix this?
I'm using openvswitch.


This is the network config:


source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface enp0s31f6 inet manual

iface enp1s0f0 inet manual

iface enp1s0f1 inet manual

allow-vmbr0 bond0
iface bond0 inet manual
ovs_bonds enp0s31f6 enp1s0f0 enp1s0f1
ovs_type OVSBond
ovs_bridge vmbr0
ovs_options bond_mode=balance-slb

auto vmbr0
iface vmbr0 inet manual
ovs_type OVSBridge
ovs_ports bond0 management20 school60

allow-vmbr0 management20
iface management20 inet static
address 10.69.20.245
netmask 255.255.255.0
gateway 10.69.20.254
ovs_type OVSIntPort
ovs_bridge vmbr0
ovs_options tag=20

allow-vmbr0 school60
iface school60 inet static
address 10.69.60.245
netmask 255.255.255.0
ovs_type OVSIntPort
ovs_bridge vmbr0
ovs_options tag=60



thanks in advance. :)
 
Hi,

what version of OVS do you have installed?
I would try it with normal Linux network model, because you have a simple configuration.
Or do you need OVS for a special propose?
 
Hi there,


Version 2.7.0.
But I've had it over the course over half a year now, that it wouldn't work with both network cables plugged in.
I've had some (well, some.. a lot) weird problems with the standard Linux Bridges with VLANs. OVS works great, except for the non functional static LAG..
