Hey @Ebelloli sorry this slipped under our radar, would you be able to get us the full logs from your device so we could take a look at what went wrong with the fs expansion logic?
You can get them with
sudo journalctl | gzip > journal.log.gz
You can DM it to me if you don’t want to post your logs publicly.
Also does rebooting solve the issue? The filesystem expansion logic runs on each boot so potentially if something went wrong on the first boot and reboot could resolve it.
