How to resize a Penetrator Proxmox Image?

1. Proxmox: Stop VM → Hardware → Disk → Resize → add e.g. +20G.
2. Boot ISO: Attach GParted Live (or SystemRescue) ISO → boot the VM.
3. Extend partition: In GParted, select the disk (often /dev/sda or /dev/vda), right-click your root partition (e.g. /dev/sda1) → Resize/Move → drag to use all free space → Apply.
4. Reboot into Image → verify: df -h /.

GParted will run resize2fs automatically.
