OMV UI not executing SMART settings

  • Hi there,


    recently i found out that the SMART settings under Storage -> Physical disks are not executed by the UI on my system. Although i have SMART activated for all drives but the system drive under S.M.A.R.T -> Drives.


    I have three WD RED 3TB and a SSD system drive in my system - two WD RED drives as RAID1. As WD REDs don't support APM, i disabled the APM feature as well as write cache. For spindown time i set 30min. But the drives never fell asleep. SMART checks are set to every 14400 seconds.
    Interestingly setting manually in terminal

    Code
    hdparm -S 241 /dev/sda ... to sdc


    worked. And the drives fall asleep which can be confirmed by

    Code
    hdparm -C /dev/sda ... to sdc

    So i am happy that it works but i ask myself if the OMV UI executes the right commands in the background?


    I am using OMV 4.1.4-1.


    Best regards,
    B.

    Have you checked /etc/hdparm.conf if there are the correct settings? hdparm is now triggered via UDEV, so there shouldn't be any problems. OMV tries to use predictable device names (/dev/disk/by-id/xxxx) in /etc/hdparm.conf, but in some cases the system does not provide that. If device names like /dev/sdd are used in the config file, this can be the reason for your troubles because such device names can change every time, so a specific device gets a different device name each reboot and may confuse hdparm.

    Yes, looks fine to me:


    By using "by-id" with hdparm -C dev/disk/by-id/ata-WDC_* i receive the information that the drives are in "standby" status.

    Keep also in mind that a drive never falls asleep if there are read/write activities. You need to find out if there is something reading or writing to your devices.


    Yes, i thought about that but i found nothing with iosnoop, so i tried to set the spindown time manually in the terminal with "hdparm -S" and the drives spindown perfectly as they should.


    Some more ideas:

    • I installed OMV over a Debian minimal installation, could this be causing problems?
    • hparm seemed to have problems with WD REDs (see here). But i nevertheless i can set it manually and the drives react on that. On the other hand i have some other problems with SMART and the WD REDs (see here).
