hi there,

just set up a cluster with a weird behaviour:

it takes +5 Minutes to bring up the bridge after clicking apply configuration

/etc/network/interfaces:
Code: 
auto lo
iface lo inet loopback

iface enp65s0f0 inet manual

iface enp65s0f1 inet manual

iface enp65s0f2 inet manual

iface enp65s0f3 inet manual

auto enp33s0f0
iface enp33s0f0 inet manual

auto enp33s0f1
iface enp33s0f1 inet manual

auto enp34s0f0
iface enp34s0f0 inet manual

auto enp34s0f1
iface enp34s0f1 inet manual

auto bond0
iface bond0 inet static
    address 10.60.104.2/24

    bond-miimon 100
    bond-mode active-backup

    mtu 9000
#Ceph Cluster Network

    bond-slaves enp34s0f0 enp34s0f1
    bond-miimon 100
    bond-mode active-backup
    bond-primary enp34s0f0

auto vmbr0
iface vmbr0 inet static
    address 10.60.101.16/24
    gateway 10.60.101.254
    bridge-ports enp65s0f0

auto vmbr1

Also booting up the Machine takes ages, as the network interfaces take such a long time to come up.

This time i also got messages, but from other parts of ther kernel (mainly inside the mlx5 driver)

Hi,

what is the exact model of this Mellanox NIC?
And do you use the actual firmware on it?
 
I have tested it here with a Mellanox connect-X4 LX EN OCP 2.0 Type 1 Form Factor.[1]
I have used your network setting, and everything is working.

The working Ubuntu 20.04 LTS/Fedora may not use all functions on this card.
If you are still interested to reproduce this error on Ubuntu/Fedora, we can send you a script where all functions are set manually.

Hi Wolfgang,
i'd apreciate if you could send me the scripts.

I have a bunch of other Servers all with those standard PCIe Connect-X4 LX EN running with PVE, but none uses a vlan aware bridge - so i never bothered ;)

Thanks for your help :cool:

Hi There,

i just got an experimental firmware release from mellanox for this specific card - and the "link down" issue is now gone.
The startup of the vmbr with vlans is still somehow "shitty" as it still takes about a minute or so to bring up the nic (before it was about 3 minutes) - is this behaviour somewhat "normal" - like bringing up vlan aware brige "usually" takes longer that non vlan version?
 
I guess this can be handle with restriction the VLAN range.

Code: 
bridge-vids 5-15 103 200-205
