Just out of curiosit, what do you gain from unmounting the fs? Depending on your reasoning, it might he an option to use a zfs filesystem, set it up so automatic jobs rarely run and then set a somewhat agressive disk spin down policy. That way fs info would be handled by the arc, not the disks and they would only spin up when an actual file is accessed.
At least I assume it would work this way. Look-Ahead reads or your explorer generating previews, etc. might well make thta option fail.

Good question, as it’s not really obvious from the post. There’s simple stuff such as energy savings, preventing unneeded file indexes, preventing corruption, etc. The biggest reason is mostly situational to me, as I’ve taken over a bunch of drives from friends who renewed their own, which have been running in their respective NAS setups. The drives are definitely not new but have a reasonable remaining life span. I kinda realized that I don’t need the media files to be available at all times, so to squeeze the most out of the drives, I wanted to try this strategy.
I haven’t yet tried adjusting spin-down options as it’s more predictable when I “manually” spin the drive up and down. I’m afraid the random seeks will still spin up the drives several times a day and hurt them over time.
