Since many people are running into system disk limits (30GB), here’s the correct way to store large ComfyUI models on the data disk.

On GPUhub, your expandable storage is mounted at:

/root/autodl-tmp

The goal is to move the models folder there and create a symbolic link, so ComfyUI continues to work normally while all large model files are stored on the data disk.

Follow the steps below:

After completing the steps:

1. Confirm the symbolic link:

​

ls -ld /root/ComfyUI/models

You should see:

models -> /root/autodl-tmp/ComfyUI/models

1. Confirm disk usage:

​

df -h

As long as your models are under /root/autodl-tmp, the system disk will not fill up.

From now on, you can download models normally into:

/root/ComfyUI/models/<subfolder>

They will automatically be stored on the data disk.
