Help To increase root partition

[Elberton (GJ)]

NethServer Version: NethServer release 7.9.2009
Module: Nextcloud / Active Directory Client

Hi all.
I am preparing for a future saturation of my virtual hard drive.
My Nethserver is installed on a Proxmox Hypervisor.
I assigned it 320 GB, it is at 94% usage.
I increased the size of the virtual disk to 420 GB.
How do I increase the partition?

i have set a df -h

Thank’s for your help

If you click on the harddisk there should be “Shrink”/“Grow” buttons:

Here is the wiki documentation about increase partition on Proxmox VM on command line.

You could also use growpart.

Than’ks for your help.
I do that on command line because on webpage i didn’t have Shrink or Grow.
