Proxmox Space full, Access denied

[MarshyMelloow]

Hello, back when I first got a used server I installed proxmox on it, I was so excited that I installed it on my main storage drives. That storage is now full and when I start it I get the following errors:

[Failed to start] Proxmox VE Cluster File System
[Failed to start] Proxmox Firewall
[Failed to start] Proxmox VE Scheduler
[Failed to start] Proxmox PVE cluster HA Resource Manager Daemon

Also when I login with the webgui I get Accessed Denied, I also get the same message within the command line doing commands like "qm stop 000". What should I do? I have X2 2TB Drives arriving tomorrow. Should I just try to add the new drives to my existing storage, if so how would I go about doing that?

Thanks for the help in advanced!

First I would log in using SSH and then free up some space by deleting unneeded data like old log files in "/var/log". Removing old snapshots can also free up alot of space.
