• OMV 2.x
    • I have an Openmediavault server with 3 drives installed and they are setup as
      /dev/sda - Hitachi HDS72103 - temperature 29 Celsius
      /dev/sdb - ST4000DM000-1F21 - temperature 30 Celsius
      /dev/sdc - ST4000DM000-1F21 - temperature 30 Celsius

      I enabled Storage > S.M.A.R.T
      General Settings
      Check interval: 1800
      Power Mode: Never

      Temperature Monitoring
      Difference: 0
      Informal: 0
      Critical: 0

      Question 1: what the value numbers should I set for Difference, Informal and Critical? What is your recommendation according to your experience?
      Question 2: Is it recommended to use S.M.A.R.T at all?

      Thank you a lot
    • Well I cannot really help you with the temperatures, because it is really what you define as an acceptable temperature for your hard drives. Something to keep in mind though, is that a drive shouldn't really get any hotter than 50 degrees Celsius.
      If you want a suggestion, I would say to set the critical temperature at around 45-50 degrees.

      However, as for using SMART, it would be smart (pun not intended) to leave it on as it can act as an early indicator one of your drives is about to fail. I've recently experienced this myself. Detecting those errors early can help prevent you losing data.
      There isn't really any downside to leaving SMART enabled however.
