Hi all,
Running the latest version of the 6 branch (6.12.15), but this problem has started some time last year I think. I've been using this server for a long time, and the drives always used to spin down when not in use after two hours, which I believe is the default setting.
But at some point they no longer did spin down, or at least they no longer stay spun down. Looking at the logs, it seems the system reads the SMART info shortly after I spin them down manually, which mean within a minute or so they are back up. At least that's what it looks like to me:

Any idea what could cause this phenomenon? I don't want my drives to be spinning all day long when I only need them occasionally during the day.
Thanks!
