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

    Never had mdadm causing that. I have a raid5 array that’s used only for backup once a day and it is mounted 24/7, and the disks are off for 23hba day more or less …

    You can try and figure out what’s accessing the array:

    fatrace | grep /mnt/mountpoint/

    This will show you the process, type of access (read, write, open, etc), and path. If you don’t see anything right away just leave it running for a bit.

    mdadm --stop /dev/mdX should at least tell you whether or not mdadm is causing the spinning.
