Proxmox VE 9.0 Installation on a Supermicro CSE-829U Server

[Phoenix85]

Hi,

Installation in a ZFS 1 so mirrored wasn’t an issue and worked flawlessly.

My issue seems to be the Intel X540 Network Controller on the Server Mainboard.

Mainboard of Server X10DRU-I+ from Supermicro

The Network Bridge vmbr0 is down

I tried the allow unsupported SFP =1 but that didn‘t help

I have pictures but the forum always says they are too large.

Any idea how to fix it?

Please provide the output for:

~# ip a 
~# cat /etc/network/interfaces
~# pveversion -v

Also try:

lspci | grep -i ethernet

You should see the X540 entries.

Router is a Ubiquiti Dream Machine Pro SE with Gateway 192.168.1.1

I have Fiber Glass connection from Deutsche Telekom in Germany.

192.168.1.57 and 192.168.1.173 are my both Pi-Holes.

I also have a single Intel I210T1 PCI-Express card here for testing if needed.

Does the physical link appears to be Up? you can check if it detected with ethtool:

ethtool enp1s0f0
...
        Link detected: yes

what happens when you try to manually bringing the vmbr0 up?
~# ifup vmbr0

ethtool:

 

[Phoenix85]

ifup vmbr0

From the earlier provided output of lspci | grep -i ethernet you have also Gigabit NIC:

For lspci |grep-i ethernet

Is the cable plugged in to the Gigabit NIC now? or are you plan is to use the 10-Gigabit connection? I think the Gigabit is correspond to ens2 (altname enp3s0)

If you want you can give it try and use it instead of Intel X540 10G card. Connect the cable to the Gigabit NIC and update your interfaces file to use ens2 instead of enp1s0f0. then try to bring the interface up with ~# ifup vmbr0


As you know, the message, Link detected: no, means that your network interface is not detecting a physical link (e.g., from a cable or switch). It could be:
1. Faulty or unsupported NIC
2. Bad or incompatible SFP module (if used).
3. Incorrect speed/duplex settings.
4. Cable is not properly plugged in at both ends (PVE and the switch/router/modem) or faulty one, (Pretty sure you did those check but just writing it just in case).

By the way, you can easily share the output of the command in a code block using the code icon in the forum toolbar, instead of attaching it as a screenshot.

At the moment an Ethernet cable is in IPMI Port and one in the Intel Gigabit NIC.
My plan is to use the 10 GBIT connection if possible. But at the moment it doesn't work.

I will test the Gigabit NIC later if that will work out of the box.

1. Don't think so as I have a second equal server with Proxmox Backup Server where I also can't get the 10GB ports to work .... yet
2. I don't think they have SFP Modules --> it's pure copper RJ-45 isn't it?
3. -> should I check this in my Ubiquiti Console?
4. Faulty one ... I had a few min ago a Hue Bridge Pro on it without any problems.

ens2 instead of enp1s0f0 --> how can I change that in the interfaces?

Is it via this command cat /etc/network/interfaces ?

And if, how?

Thanks
