Hello.

Is it possible to check and observe the SMART informations of the harddiscs (bad sectors etc.) in a NAS326? Perhaps with a log. To show and save every change (new bad sector etc.).
If the counter is rising, i will call the seller of the used HDD.

And is there a automatic alarm, if a HDD in a RAID 1 does not work?
Without alarm, i can not change the defective hdd. And when the second HDD is defect, all data are lost.

    The 'normal' smartctl tool is available. To see the smart values execute (as root)

    smartctl -a /dev/sda
    smartctl -a /dev/sdb

    If you want to monitor some specific value, you'll have to write a script for that.

    AFAIK the NAS has an automatic alarm when the array get degraded, and maybe also when SMART tells the disk is in danger. But I haven't experienced them.

    I have a trouble on the NSA 325v2 with these commands. I have bought 2 6tb seagate ironwolf pro drives, but running smartctl -a /dev/sda gives:

    smartctl 6.6 2017-11-05 r4594 [armv5tel-linux-2.6.31.8] (localbuild)

    Device does not support Self Test logging

    which is weird. I tried both entware and stock smartctl. Are these drives too new for the NAS to be able to read SMART values?

    On a 325 (and other Kirkwood devices) the sata chip has to be specified.

    smartctl -d marvell -a /dev/sda
