I want to use the mergerFS-Pool as Mediaserver containing large files in different directories and I don't want to care about where I have to create new directories. If possible I'd like to use the drive on which a directory first was created and write to exactly this drive until it is full and then automatically mergerFS creates right this directory on another drive in the pool where most space is available.
This should prevent OMV to spin up all drives but only the drive I'm working with a directory.
Am I thinking wrong here or is there a perfect policy for me? Which would this be?
