Total Newb: Locked out of OMV5 after powercut. No passwords recognised. Desperate for help...

Hi,

As a result of a power outage (I guess) my OMV 5 file server won't mount on my Mac. It has been running perfectly up until now.

When I try to log in over the CLI, no password is recognised. I know the root password is correct as I have used the CLI before, to replace a RAID disk. Now it's not recognised.

I'm connected directly to the server now and I see the OMV prompt. I was hoping to be able to run omv-firstaid but I need to be logged in for that...

I found this: https://www.softzone.es/linux/…ar-contrasena-root-linux/ but I don't ever see a GRUB menu.

At the OMV login prompt, when I try to enter my password where the username should be, I notice that when I try to type a £ sign (Mac keyboard), which is part of my password, it's not recognised. A "3" appears. Could this be why my password isn't recognised? It contains both £ and $. In Unicode you're supposed to be able to type "Option-shift-U-003" to get a £ sign but I can't get this to work either...

What can I do please?

When you say "cli", do you mean ssh or local console?

At the moment I'm connected directly to the server with screen and keyboard but nothing works over the network either...

If you boot from the Debian netinstall iso, you can choose the repair option and change the root password.

Just so I'm clear... I can create a bootable USB stick and go from there...? https://www.debian.org/CD/netinst/

yep

Well... I couldn't get that to work but by some miracle my original root password was recognised once I rebooted back into OMV...
