Shrink HDD of cloudinit template

[ca_maer]

Hello,

I'm trying out cloudinit to deploy our VMs and so far everything is working fine. I've followed the tutorial in the doc to create the template which worked fine.
The template had a 3GB HDD (scsi0). I wanted to extend the disk of another VM and by accident I extended the disk of the template to 50GB.

I'm trying to shrink it back to 3GB but I can't seem to be able to. Here's what I've tried:

1. Boot in live CD and shrink using gparted
2. set zfs volzise to 3GB
3. Change the .conf file to reflect the new size

No matter what, it seems something is changing it back to 50GB every time. Could it be cloudinit ? I've tried to 'regenerate image' but to no avail.

How would I go about this ?

Thanks

Hi,
do you use any snapshots?
maybe a rollback set it back to 50G.

Hey Wolfgang, fortunately I did have a backup so I restored from it. I was wondering if it was possible without rolling back a snapshot or restoring a backup
