I got a similar problem like thread bellow, just with MotionEye.
I got this:
There is a path to the system drive.
I can't change it to anything via GUI:
I tried to change the path to:
- /srv/dev-disk-by-label-Data/MotionEye:/srv/dev-disk-by-label-Data/MotionEye #File Storage
but it's still creating a folder in var/lib
