Proxmox Web GUI not accessible after second NVME Drive

[sidnakvee]

Hi ,

I just added second nvme 1Tb to proxmox server. System boots up norammly no beeps no issues. However when it reached to proxmox screen for roo password it stays there for few seconds then goes blank and stops. I also notied the attched LAn card also do not blink at all. However once i removed the second nvme it work fine.
However its new nvme drive and BIOS detects it and dnt seem any issues with it .

Any work around or settgins please feel free to share.

Regards

With adding NVMe-device your PCIE-IDs change.

That could be really the brand or the cheapest s...tuff.

More likely:
Dive into the wonderful world of limited PCI-E Lanes.
ryzen 3700x -> has 24 lanes
Nvidia RTX 3060lhr -> makes 16 lanes go poof
1x NVMe-Slot -> makes 4 lanes go poof (or already throttled@2 because nothing is left, onboard NIC wants lanes and SATA-Controller too)

Nothing is left, another card wants some lanes...and mobo decides to kick off the NIC. Be it intended, be it an error, but not unusual.

If you really want/need more lanes, use Threadripper or Epyc platform...

Read from "Check PCI-E IDs via lspci with and without the card...."

runing the command lspci shows lots of entries what to do next and what to look for kindly explain a bit to reslve this issue . thansk again

see entry for new nvme drive as Non -voliatle memory controller : sandisk corp WD black Sn770 Nbme SSD (rev 01)

 

[mr44er]

nano /etc/network/interfaces <- this is your network config before you put in NVMe

There is the "old" working NIC-Name inside configured with the IP.
I don't know that name what you have...could be eth0, eno0, eno1...
If you add PCI-E device (card or NVMe doesn't matter), sometimes IDs change +1

So the new NIC(portname) changes +1.

new nvme drive as Non -voliatle memory controller : sandisk corp WD black Sn770 Nbme SSD (rev 01)

Good.

So IDs got +1 -> Now check ip a what new NICname you have.

Replace that new NICname with all old NICname entries in nano /etc/network/interfaces + reboot

Thanks so I got the old ones as in /etc/network/interfaces:
enp6s0
enps0f0
enp7s0f1
vmbr0
vmbr1
vmbr2

Output of ip the new entry i can see is :
wlp6s0 so add this in /etc/network/interfaces as like what
Previo sone has #WAN , #LAN and #OPT

 

[mr44er]

Ok, with 3 you need to be more careful.

enp6s0
enps0f0
enp7s0f1
^
If these are the old ones, check with ip a what is new.

Replace in /etc/network/interfaces what is new and only that. Could be just one or all 3.

[sidnakvee]

Thanks a lot added this but issue still not resolved .
auto wlp6s0
iface wlp6s0 inet manual

 

[Kingneutron]

wlp6s0 is Wireless, not what you want

 

[sidnakvee]

oh ok but thats the only new identified from ip a all others already identified however when tried ethtool on already setup interfaces like enps6so , enp7s0f0 and enp7s0fi showing no device matching names of either one .

Attaching my ipa and /network/intefrcaes file . Kindly review and help thanks running all thee cmmands for recovery mode as main interfcae comes for secnd then goes blank.

The adding of a PCIe device (your NVMe) shifted each network device PCI ID up by 1.
Change enp6s0 (in /etc/network/interfaces) to enp7s0 (like shown in ip a).
Change enp7s0f0 (in /etc/network/interfaces) to enp8s0 (like shown in ip a).
Change enp7s0f1 (in /etc/network/interfaces) to enp8s1 (like shown in ip a).
Reboot.

Thanks a lot for your help did what I was told but still same issue screen goes blank . please check attched image if I am mkaing any mistakes thanks again !

oh after rebooting network and then reboot see that proxmox sever running but screen went blac as it used to be i can login ro proxmox server but cant see display on monitor though !
