Not being to able to run OMV 6 without a graphics unit

Quote from Solid Kuro

Am I missing something here or is it intended to work this way in OMV 6?

OMV6 is just an application sitting on top of operating system Debian 10, hence a "headless" operation is definitely possible.

Did you enable access via ssh before removing the graphics card?
Using ssh/putty checking for errors during boot via dmesg is the recommended approach

If I remember correctly, there are some boot option to set, so that the kernel does not try to initialize a graphics card, but assumes text mode.

Google may help if you point it in that direction.

seems the best advice

Try this one: RE: Fehler beim Booten ohne Monitor

Whenever I try to start the server with my graphics card out, I'm getting "Software Failure" on web interface

This happened to me initially and still does sometimes, try Ctrl + Shift + R the refresh should work

"Network error: connection timed out" on PuTTy

Highly likely that the ip address has changed after the reboot, check your router, one way around this might be to set a static ip address on the initial boot (before you shutdown and remove the graphics card). However you need to check your router they all behave differently, as an example mine has a dhcp scope from 65 - 253, so any address before 65 can be used as a static ip, some will allow an option to 'always use the same ip address'. But again you need to set this before the shutdown.

My OMV server has a static IP on local network, so this is not the solution either

how, as this statement has been on here before, can you ping the ip address of omv

You might try using a "serial console". I have not done it in many years but google can tell you how to do it. I think you should be able to set it up and then remove the card. But you might need to do a "serial console" install. Then restore a backup.

Good luck

Put the graphics card in and boot, check the logs from the previous boot (if any).

If you have systemd's journal set to persistent (should be the default) you can check previous boot logs with journalctl -b -1

If there's no logs then it's not even booting, which means problem could be with bootloader (grub) or the BIOS that fails to boot without a GPU (though it would be weird if it booted fine before and you didn't change anything in the BIOS settings...). Sometimes BIOS also issues a warning and waits for keyboard press (usually F1) to resume...

This could be my problem:

OMV server without graphics-card or on-board GPU (SOLVED)

A common goal is to repurpose an old PC as an OMV server. This is straightforward but it is preferable not to have a powerful graphics card eating up power on the PCIe slot. Here is how I managed to get a motherboard (with no on-board GPU) to operate without a graphics card.

You will have to buy a cheap PCI card such as this one, but it can eventually be removed completely at the end of the process.

The core problem here is that you need graphics to install OMV but if you then remove the card and…

The question is if there's a way to fix it without a PCI card (I only have PCIe ones).

Interesting!

I've never come across anything similar, but this would explain why it worked in older versions... probably the device was named eth0, regardless of the pci address and now it's the utterly awkward enp?s?? naming scheme...

I'm sure there are other ways of working around it... I think there are ways of forcing the old network device names, so you could try that. For example try the grub options mentioned here: https://unix.stackexchange.com…rk-interfaces-in-debian-9

There might be other ways... because on my desktop debian machine, my ethernet device is called eno1 and then ip says it's also known as enp0s31f6

Output of ip a:

2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 1c:69:7a:6f:1d:f5 brd ff:ff:ff:ff:ff:ff
altname enp0s31f6

Not sure where this eno1 comes from though...

I also remember in some old computer running debian, after a release upgrade it maintained the eth0 name (this might have been an upgrade from debian 9 to 10 though, not debian 11), while on a clean install of the same debian version (again might have been debian 10) it assigned the same device the enp?s?? name.

Yet another possibility, if you have an USB ethernet dongle, you can connect it and it should still have the same name after removing the GPU, so you could then connect to OMV through the USB ethernet and reconfigure the internal ethernet from there...

One other could be removing the OMV OS disk from the computer, connect to another computer and edit the configs and change the network device name (you'd need to know the name of the device after removing the GPU, but that should possible by reading the logs in the disk).

This assumes your OMV is actually booting. Set OMV to dhcp. Set up a static reservation for the mac address on your router or dhcp server. This should give you the address you set there. No matter what the device name is.

To see if it is booting watch the hard drive activity light with and without the card. It should be about the same for both.
