Stopped booting

[siggib]

My Proxmox box has been running fine for months, and then all of sudden crashes and won't boot. I am not the most savvy linux admin but I usually can scrape by with little web search. I'm not figuring out how to get the box to boot again. Anyone have any clues for me? Here is a picture of the screen. I think the most significant line is

run-init: can't execute '/sbin/init': input/output error

Again this was working fine then just crashed. What am I dealing with here? Disk failure? Bad block? Bad update?

Anyone have any clues for me?

The issue (for me at least) is that Proxmox VE ships with "quiet" boots, it would be good to have it boot with full output, see here:

That will not fix your issue but you get more context on why it can't even find init.
