• Spindown logic in RC2?


    CS01-HS

    I don't know if this is a bug but I wasn't sure where else to post it.

    I have two spindown problems in RC2:

    I've set default spindown to 15 minutes to help with testing.

     

    (1) The USB disk in Unassigned devices

    Unraid tries to spin it down (good!) but doesn't actually do it. That may be a problem with the drive's USB interface so I've cron'd a user script to spin it down with hdparm -y /dev/sdb (which works.) It looks like unRAID never detects that it's spun down (or a successful return from its own spindown call) because absent drive activity I see this every 15 minutes in the log whatever the drive's status:

    Dec 20 06:45:05 NAS emhttpd: spinning down /dev/sdb
    Dec 20 07:00:06 NAS emhttpd: spinning down /dev/sdb

     

    (2) The Fast pool

    These are 2.5" 7200rpm WD Blacks which also don't spin down. I see nothing in the log indicating unRAID attempts to spin them down except when I trigger it manually with the Web GUI

    Dec 19 21:09:57 NAS emhttpd: spinning down /dev/sdj
    Dec 19 21:09:57 NAS emhttpd: spinning down /dev/sdf
    Dec 19 21:09:57 NAS emhttpd: spinning down /dev/sdi

     

    I've attached diagnostics but this is more a request for information. Should I see spindown calls for Pool drives in syslog?

     

    (I should mention I haven't seen the array disks spin down either but they're set to 2 hours and haven't really had a chance. I'll lower it and keep an eye out.)

    How could I tell?  What is it?  would it be causing my drives to stay spun up? How can i stop it?

     

    They only spin down if I tell them to.  Where they used to only spin up when needed.

    Found my issue. RESOLVED for me.

    Grafana Unraid Stack (GUS) Docker. ill go there for support.

    Right.

     

    Specifically it's the smartctl calls in telegraf (part of GUS.) Alternatively you can comment out the [[inputs.smart]] block in Grafana-Unraid-Stack/telegraf/telegraf.conf to disable them.

     

    Seems for whatever reason (new kernel, new smartctl) these calls are recorded as disk activity which causes the disks to fail unraid's "If inactive for X minutes, spindown" test.
