Resize VM disk via Proxmox

[jtvdw]

Hi,

I tried increasing the VM's disk via Proxmox but it still stays the same, what can I do to fix this.

Thanks in advance.

What OS is your VM using?

 

[jtvdw]

Running ubuntu 16.04.

Have you updated 16.04 with the new disk information? Are you using LVM?

 

[jtvdw]

yes, updated 16.04 (what do you mean wit hthe new dis information) and using lvm yes.

Resizing the disk is only the first step. You must then enlarge the partition inside the virtual disk, then finally you have to enlarge the file system in the partition on the disk.

You can find the full instructions here.

okay but I followed this steps in the link send but still shows the original size of the disk (maybe I did something wrong), what can I do to fix this. Must I post any outputs of my system here?

Here are the steps that I follow when increasing the size of the disk:

01. Turn off the virtual machine.
02. Back up the virtual machine.
03. Extended the disk using web GUI.
04. Boot the VM using Ubuntu Desktop install ISO and select try ubuntu.
05. Launch Gparted.
06. Right Click on both sd2 and sd5 and chose "Deactivate".
07. Resize the extended (sda2) partition.
08. Resized the LVM (sda5) partition.
09. Boot up the VM.
10. Execute the following Commands:

a. lvextend -l +100%FREE [mount point]

example: /dev/vrtemlsrv-vg/root​

b. resize2fs [mount point]

example: /dev/vrtemlsrv-vg/root​

11. Restart and confirm updated drive size.
