no network interface found with QLogic FastLinQ 41264

[alain]

Hello all,

I tried today to install Proxmox Backup server on a Dell PE R740. It was my first try at it. It stopped wit 'no network interface found'. The server has a QLogic FastLinQ 41264 with two SFP+ ports and two Ethernet 1 Gg ports. The problem has already been reported for such cards with other installers, for example Proxmox VE (with PE R640).
I tried the workaround described in this thread, that is to create a dummy interface under a shell interface (Ctrl F3), then abort the installer, and reluanch it with xinit :

abort installer
modprobe dummy
ip link add dummy0 type dummy
ip a
xinit

See : https://forum.proxmox.com/threads/no-network-interfaces-found-qlogic-4xxxx.42892/

But in this case, it does not work, because abort and reboot does the same thing : reboot the server.

I use the 1.1-1 iso installer, which has a kernel : 5.4.106-1-pve kernel (uname -a);

Would it be possible to add the QLogic FastLinQ 4xxxx driver to the kernel, or is there any other workaround to this problem ?

Best Regards,
Alain

Have you tried installing PBS on top of plain Debian already?

Hi Dominic,

No, I did not try, because I thought the problem arised from Debian and non Free drivers. So I thought it would not install under Debian too. But, indeed, you don't use the same kernel.
Now, the server is reinstalled under Rocky Linux (for another backup solution), and as I expected, as it is a RHEL clone, and Dell servers are suuported for RHEL, the installation went flawlessly... For now, I cannont try alain with Debian...
