Bond as part of bond


Jun 29, 2020
in my setup I have 2x10GBit Link balance-rr. Normally I would like to use alb, but I read somewhere that this needs driver compatibility and I wanted to keep it simple. As I have 4x6TB RAID 10 10GBit ist plenty.

But I want to add the GBit ETH in a bond as backup Interface if the 10GBit Card fails.

So I configured as I did on quite some PVE machines
bond0 enp6s0f0 enp6s1f1 balance-rr
bond1 bond0 enp5s0 active-backup bond primary bond1

but PBS, other than PVE, prompts me with an error there
bond 'bond1' - wrong interface type on slave 'bond1' (Bond != Eth)

As I do understand that the GUI seems to only accept eth Interfaces in a bond, that is new to me and I would like to know if this is a bug.
i think you have a problem here :
bond1 bond0 enp5s0 active-backup bond primary bond1

i think it must be:
bond1 bond0 enp5s0 active-backup bond primary bond0

The primary bond for the bond1 is bond 0 and not bond1 itself

Well thats a typo, I did indeed type it correctly and the error states bond!=ETH

therefore thats not the problem.
