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) | ||

Before making any changes, you can confirm the current size of your disk. | |||
* On Proxmox web gui: | running `fdisk -l /dev/sda`, this lists partition table details of /dev/sda, showing its total size and partitions. | ||

Next, to increase the disk 'physical' size: | |||

* 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. | |||
