Well, from this part of the text, I had presumed the machine was down:
"Here's how I expand the available disk size.
First I increase the virtual disk in the hypervisor.
Then I fire up the VM and do the following:"
What I do can be made with the machine online, but partprobe many times
refuses to find the new size of the partitions, then, I just programe this
on my maintenance window and shut all down. Made all the changes and
upgrades necessary at once.
