Hi @westcoastdaz,
Here is a comment I just made in another forum post which may explain why storage space keeps increasing: Balena Supervisor Not Pruning Dangling Images
In short, the Supervisor does not handle image management in local mode, only upon switching to and from local mode. To resolve your SD card’s size being taken up, you could try balena system prune on your device to clear out unused images/containers/etc. Please note that this will remove all unused containers, images, and networks on the device (not volumes though). Please let us know if this works!
Regards,
Christina
