	~~This is for increasing~~ a disk~~'s size~~.		When a virtual machine (VM) needs more disk space, you can expand its storage by resizing the disk in the Proxmox GUI and then adjusting the partition inside the VM using Linux commands.
	These steps only work if the root partition is at the end of the disk. (The automated install config/preseed ensures this)		These steps only work if the root partition is at the end of the disk. (The automated install config/preseed ensures this)

	To increase the disk 'physical' size:		Before making any changes, you can confirm the current size of your disk.
	* On Proxmox web gui: ~~select disk, click the '~~Disk Action~~' dropdown and select '~~Resize'		running `fdisk -l /dev/sda`, this lists partition table details of /dev/sda, showing its total size and partitions.

			* Enter the new disk size and click OK

			After resizing in Proxmox, check if the disk size change is recognized by the system by running `fdisk -l /dev/sda` again
			The total disk size should reflect the increased value. However, partitions remain unchanged. This means the top layer is aware of the size increase
			now we need to inform the other layers.

			If the total disk size does not show an increase as expected, you may need to run `partprobe` to force the system to re-read the partition table without requiring a reboot.
