I have an Ubuntu 21.10 VirtualBox VM set up with a 100GB zfs drive.
I have extended that to 500GB, because the system is a victim of its own popularity.
However, I am at a loss to growing that to fill all the free space.
Part of it is that I am not sure what I should see when I'm done.
Should I still see "free space" but zfs will just magically grow into the free space, or should I see that pool (rpool) resized taking up the free space?
The basic steps I followed are in the following code segment.
Am I doing anything wrong? Commentary, correction etc please

### Then reboot...
Then it seemed that "all I needed to do was this"
Step 1 - Run parted
parted
print [gives the partitions, in my case 1..5]
print free [shows up the free space, and in particular the end -> 537GB]
Step 2 - Use parted to resize
resizepart
Partition number? 5
End? 537GB
Step 3 - Reboot
Except it didn't work, despite showing that rpool was all 500G as intended, data transfer blew out at 100GB, the original size.
I'm at a loss...
