You could make a copy of the VM, and see if you can resize things with
the copy and see if it breaks?

Hi,
I'm currently fiddling with KVM, Proxmox and various VMs.
I setup a very basic VM with a manual (fdisk) partitioning scheme: one /boot
partition, one swap partition, and one root partition, the latter being the
last partition and thus expandable).
I'm starting with a reduced disk size (6 GB in total) and a minimal
installation. The idea behind this approach is that I can clone this minimal VM
and then eventually expand it to fit my needs.
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:
# yum install cloud-utils-growpart
# lsblk
# growpart -v /dev/sda 3
# resize2fs /dev/sda3
Now here's my question (finally): is there any risk involved in this sort of
operation? Or can it be performed on a production system without having to
worry about data loss?
Cheers from the sunny South of France,
Niki
