Pcie Sata position cards vs. network card - strange issues

Can you post the output of ip a ? (when all cards are inserted)

Contents of /etc/network/interfaces as well as output lspci -v would be interesting as well
 
I am not able to connect to the server in case all cards are inserted. .... is it somewhere in the journal?
 
Ah yes of course. I think the problem is as follows:

By inserting the additional PCIe card the identifier of your NIC changes. This causes your network configuration to be invalid, since it is now referring to a network card that has a different ID. You need to check what id is currently configured (in /etc/network/interfaces) and then check which ID gets assigned when you insert the new PCIe card. Then you would need to change the ID of the NIC in the network configuration. This would be easiest if you can attach a display and keyboard to the server temporarily and then make all the necessary changes.
 
Yea, I thought so, this makes it quite probable that the name of the NIC has indeed changed and there are some issues with configuration somewhere. The name of the interface from ip a really matches the configured interface in /etc/network/interfaces ? Because if that is the case it could get a bit tricky to diagnose, I would have to think a bit about other different problem sources.
 
I will also upgrade power source today (750 to 1000 W) , however all PCIE slots seems to be powered.
 
Ok the problem is that in interfaces is the name enp4s0 and in the ip a is the name enp3s0

ok edited the interfaces configuration and it WORKS! ... now I will see if the drive will be safely replaced Fortunately it looks like now I can ad more PCIe cards

BTW it looks like some trouble in Proxmox VE with inability to react on the changes of this kind.
