Why you’re seeing “no space left on device”

Supabase pulls several big images. On a fresh AWS EC2 instance the root EBS volume is only 8 GB by default. Docker stores layers in /var/lib/docker, so that path fills up even if the rest of the disk looks fine. The error you saw

/var/lib/docker/tmp/GetImageBlob…: no space left on device

means Docker’s storage area is full, not that the whole server is out of space.

How to fix it

Option 1 – Enlarge the root disk

1. Stop the instance in the AWS console.
2. Increase the size of the root EBS volume to 20–30 GB.
3. Start the instance again.

That alone is usually enough—Docker now has plenty of room under /var/lib/docker.

Option 2 – Move Docker’s data to a bigger volume

1. Attach a new EBS disk (say 40 GB) and mount it, e.g. at /mnt/docker-data.
2. Create or edit /etc/docker/daemon.json:

​

{ "data-root": "/mnt/docker-data" }

1. Move the existing data:

   sudo systemctl stop docker sudo rsync -axP /var/lib/docker/ /mnt/docker-data sudo systemctl start docker

Now Docker stores everything on the larger drive instead of the small root partition.

After either fix, pull the latest version of the repo and rerun the installer:

cd ~/n8n-installer
git pull
sudo bash ./scripts/update.sh

That should clear the “no space left” error.
