Proxmox not starting after install

[Colonal]

Yesterday I installed Proxmox for the first time, setup all my containers and get everything up and running. I started copying my bulk files from my PC to a CT last night.

When I woke up my Proxmox machine was shut off, I turned it on and went to work. Just got home, can't access the Proxmox web page, but I can ping and putty into it. No containers are on the network. I rebooted it for good measure, no change.

I only knew enough to get it all going, haven't had any experience troubleshooting Linux, and I don't know where the logs are. While I google to try to find what to do, does anyone have any recommendations?

So I plugged a monitor, and found it listing errors about "invalid checksum recovering blocks" and "error loading journal".
Found that I should do a pct fsck
Here's the output of the one that failed:
