I just received my new EdgeXpert and noticed that there is 2.5TB pre-allocated. Is this OEM software and can this be freed up? I have installed about 250 GB of ComfyUI models and I only have 1.1TB left on a 4TB (3.7) drive. What is inside this and do I need it? Should I reformat and re-image now after 1 day of usage?

/dev/nvme0n1p2 3.7T 2.5T 1.1T 70% /

The 2.5TB usage shown on /dev/nvme0n1p2 is not reserved space, but actual disk usage from the factory-installed EdgeXpert OS image.
To better understand your environment, could you please confirm whether any additional AI models or frameworks have been installed besides ComfyUI ?
(e.g., Stable Diffusion checkpoints, LLaMA/Qwen/DeepSeek models, Docker or NGC containers)?
For reference, you may run the following commands to help identify which directories or components are consuming the most disk space:
************************************
df -h
du -xh / --max-depth=1 | sort -h
docker system df
************************************
If the system has only been in use briefly and no critical data is present, performing a clean OS reinstall is a valid option. The latest EdgeXpert OS image and installation guide are available from the official support portal:

Thank you for your response.

The only other thing I installed before ComfyUI was VS-Code per the Spark start page instructions. The device had only been in use for 24 hrs.(now a total of 48) I have since added LM Studio and a few models but no other frameworks. My entire ComfyUI folder is 466 GB. Here is the return from the command. It does seem to have grown a bit by .3. Is this some kind of left over from when it was flashed in the factory?

tmpfs 12G 2.6M 12G 1% /run

/dev/nvme0n1p1 511M 6.4M 505M 2% /boot/efi

Thank you for your help.

Thank you for the detailed information.
Based on the df and du results, we do not see evidence of hidden factory images or leftover provisioning data consuming disk space. The disk usage appears consistent with actual data on the root filesystem.
In particular. /home uses ~558 GB, which aligns with your reported ComfyUI folder size (~466 GB) plus LM Studio and downloaded models. Other directories such as /usr. /opt. and /var are within expected ranges for the EdgeXpert OS. The 2.8T / entry shown by du represents total filesystem usage, not an unnamed or hidden directory.
One area still worth checking is Docker/container storage. The permission error suggests Docker is present but not accessible by the current user.
If any images or containers exist, they may consume space under /var/lib/docker. You may check this with:
sudo docker system df
Additionally, to rule out deleted files still held open by running processes, you may run:
sudo lsof +L1 | grep deleted
If large files are listed, restarting the related process or rebooting will release the space.

If you prefer a minimal environment and have not yet stored critical data, performing a clean OS reinstall is also a valid option.
Thanks.
 
I ended up re-imaging the device and it resolved the issue fully. After restoring the ComfyUI models I have 3.3 T free as expected. Thank you for your help.
