Resize VM Disk

Intro

This is for increasing a disk's size. These steps only work if the root partition is at the end of the disk. (The automated install config/preseed ensures this)

Step 1

To increase the disk 'physical' size:

• On Proxmox web gui: select disk, click the 'Disk Action' dropdown and select 'Resize'
• Fill in the size to increase the disk with

Step 2

To increase the disk partition:

• In the VM, first get the partition table for info (Assuming the disk is /dev/sda) with `fdisk -l /dev/sda | grep ^/dev`

Output should something like this:

• Resize using 'parted':

 * parted /dev/sda
 * print
 * resizepart 2 100%
 * quit

This is assuming that you need to resize /dev/sda2 (which the 'print' will help you determine)

Step 3

To increase file system's size:

• 'resize2fs /dev/sda2' (Assuming you need to increase /dev/sda2)
