OPNsense disk is full

[firewalled101]

I have OPNsense running on Proxmox. This VM has an assigned 80 gb storage setting on 250gb SSD. I suddenly had my drive full that the VM is no longer able to run. so I moved out some VMs to empty some space but this VM appears to consume over 200gb by itself on the proxmox side, but only 36% full on the VM side. I ran fsck -fy  / with output marking disk as "dirty". OPNsense self check marked file system fine. I can see on df -h one drive is consuming as such (see pic). tunfs TRIM is set to disable. I am unable to enable this because the disk is marked as dirty. Of note, VM is running on ext4 file system (not ZFS) and I have enabled the Discard option in HDD configuration on Proxmox side.

Appreciate help to approach this issue.
