Hello there
I want to reduce the consumption of my server and so, to reduce access to hard drives

But I suspect mdadm to access the drives frequently and wake them up.

Because even when the drives are not mounted, they wake up frequently and I can't find the reason.

Because the are not mounted, it's not due to a process.

I've temporarily disabled smartd so it's not that.

remains the software raid, who can potentially do regular checks, if that's the case how to fix it?
?

ps: I know spin down/up isn't good
