Hello all.
New to Proxmox so I am not familiar with all of the screens.. However I believe and entry is missing on my New Proxmox setup..
This server has been running for about 3 weeks and first day back from vacation none of the VM are running or will start. Data-storage units are all identified as unknown.
If I remember correctly there was a pve entry in the left list which is now not there.. Can anyone shed any light on what may have happened or how to resolve?

This is what I have checked so far: (Thanks ChatGPT)
1. Check cluster filesystem (pmxcfs)
All configs (VMs, storage, etc.) live in /etc/pve.
If pmxcfs isn’t mounted → the GUI shows empty or broken storage.
ls -l /etc/pve
Should show subdirs (nodes/, qemu-server/, storage.cfg)
If it’s empty, restart:
systemctl restart pve-cluster
systemctl restart corosync # only if clustered
Check logs:
journalctl -xe | grep pmxcfs
2. Check if storage.cfg is valid
cat /etc/pve/storage.cfg
If it’s missing or corrupted → nothing shows in GUI.
If entries exist but are misconfigured → they show as unknown.
