Unable to resize disk - Ubuntu VM - Initramfs issue

[modem7]

Hi guys,

I'm having a problem where I'm not able to resize a disk on an Ubuntu VM using Proxmox.

I've run apt install -y cloud-init cloud-initramfs-growroot qemu-guest-agent on the template to make sure the tools are there to do the task, but get stuck on initramfs with what seems like a kernel panic.

When the VM starts after a disk resize change:


Then shows:



Created the VM with Ubuntu 20.04, cloud-init (works absolutely fine bar the disk resize), and using SeaBIOS.



I'm pretty new to Proxmox/cloud-init so this could easily be an ID10T issue. Not quite sure where to start my investigation though - my Googlefu is failing me.

It seems removing the package cloud-initramfs-growroot allows things to work.

If anyone has an answer as to why it would break things, that'd certainly be a good learning experience!

Thanks!

I have the same problem with Ubuntu 22.04 have you found a solution yet?

Sorry for pushing an old article.

An answer? No.
A solution? Yes.

The only packages you should install are:

export DEBIAN_FRONTEND=noninteractive
apt-get install -y \
cloud-guest-utils \
cloud-init \
cloud-utils

From there on, it'll work.
Having cloud-initramfs-growroot installed breaks it.

Here is a script I made which installs all the relevant bits and creates a VM. Needs to be run on your proxmox host.
