hello - we use Mellanox connect-x4 for our ceph storage network.

after upgrading 1 of 7 nodes and rebooting, I can not get a connection to ceph network.

from dmesg the device name looks ok for /etc/network/interfaces :

Do you have any error message?

We have no problems with the same kernel and also mlx cards:

when using the prior kernel the ceph network works
Linux sys8 5.4.55-1-pve #1 SMP PVE 5.4.55-1 (Mon, 10 Aug 2020 10:26:27 +0200) x86_64 GNU/Linux
 
Sorry, but without an error message i can't help you ¯\_(ツ)_/¯
try sneaking around in /var/log/ceph and look at the logfiles, or try pinging nodes on the ceph public network, or check if the interface came up .. or or or

So it could be that with the current mlx5_ib kernel module that there may be a different bond mode that works? just guessing.. I remember a bond mode change needed on a kernel update a few years ago. I can test suggestions if any on the weekend
 
Have you tried updating the NICs firmware to the latest version? AFAICT the latest firmware for Connectx 4 LX is 14.28.
 
the upgrade, which was very easy using mlxup from NVIDIA/Mellanox , fixed the issue. for me this was the easiest firmware upgrade I've done. thank you both for the advice.
