Where is all my storage?

[bigblue87]

Hi everyone, first time proxmox installer here and I have messed things up pretty bad I am so lost on trying to figure out how I set my VM for storage and have no idea how to fix it. If anyone can give me help on what I did wrong here and how to fix it I would be forever grateful and will name my firstborn child after you.

Setup:
Old mac mini > Proxmox > ubuntu server > docker > portainer > plex

Storage (on proxmox)
local pve (224.55GB) this is my internal SSD
MirrorRAID (3.51TB) these are two external hard drives

On my ubuntu server, I run this command
➜ df -h

On Proxmox for my ubuntu under hardware I see this:
Hard Disk (scsi0) MirrorRaid:vm0191-disk-0,size=700G

What is lsblk showing if run inside the ubuntu guest?

So you got a 700GB virtual disk with 3 partitions and the 3 partitions only allocate 100GB so 600GB are unallocated.
So you need to create a 4th partition and format it or increase the size of the 3rd partition + increase the LVM size + VG size + LV size.
