I have a file based mount, used for nginx cache dir, so that the hundreds of thousands of little files don't clutter the main file system.



It's fstab line is the following:



/data/project/cache.img /data/project/cache ext4 discard,defaults,nofail 0 2


My problem that it cannot be unmounted cleanly at system restart. If I manually stop the nginx service and manually unmount it, then there are no problems, but automatically it generates the following journalctl logs:
