Disk/Partition size for Home Assistant

I’m running Hassio in docker that is installed on Ubuntu. The Ubuntu LTS is running on a virtual machine in Proxmox. My initial Ubuntu VM setup had a 20 GiB drive. I enlarged the the disk/partition size on both the Proxmox and Ubuntu. I now have 40 GiB total available space. Home assistant docker is still showing only having 20 GiB of total space. How do I allow home assistant to have access to the enlarged 40 GiB drive/partition? I’m using portainer as my docker manager. I have tried our friend Google with no clear answer.

I resolved this. Forgot to run resize2fs /dev/sda2 and then did a reboot
