Ubuntu VM add storage

Since my Ubuntu VM was running out of space, I needed to expand it.

Steps I used

• Expand the storage in Proxmox
• Proxmox web GUI -> Select the VM -> Hardware
• Select the Hard Disk
• Disk Action -> Resize
• Type the number of GB to add -> Resize disk
• Have the VM use the additional storage
• Proxmox web GUI -> Select the VM -> Console
• login
• sudo cfdisk /dev/sda
• sort (This should hopefully put your FreeSpace right after your Linux filesystem
• resize
• Write
• Reboot
• sudo resize2fs /dev/sda4
