I'm using PVE 8 . I created a ubuntu 23c container by downloading the template from PVE. I configured in ubuntu container samba . The disk was 16GB, I would like to extend it to 32GB. I enlarged the container disk from the graphical interface by going to resources and modification of the disk. When the container starts I see that I have more space, but how can I tell the ubuntu system that I have 32 gb? Do I have to resize the ubuntu file system? How do I do it?
