Sudden power grid failure, Proxmox can't start

[Kim A]

Hi.
I just had a sudden power grid fallout, and now Proxmox can't start.
The server starts, and I can enter "emergency mode".
From here I have not been able to find what to do.

The journalctl is not revealing anything.

Has anybody had any experience with a similar situation?

Try boot from install iso.
Debug mode install.

I have no idea what just happened. I tried to make a

fsck

to check the disk, but to no avail. Then I did a

journalctl --rotate

to get a clear overview of errors, and then I restarted, checked the journal, and still no errors - so I retried a normal reboot, and now it's up...

So whew - all is good.

But for another time, what I take from your help is, that I could have downloaded the Proxmox ISO of my Proxmox version and boot from that. But to do precisely what? Re-install Proxmox, or repair?

Thanks @milew

boot from iso and try repair system.
run fsck, repair boot problems, chceck zfs and others
