    • OMV UI Standby not working

      Hello,

      i have done a new installation of OMV on my NAS system (own build, configuration see below) but if i use the Standby function from UI the UI is switching view to xxx.xxx.xxx.xxx\shutdown.php and i see a blue screen with a red button in my browser. But my NAS seems to do nothing and it is still accessable and using the same power. If i enter the direct command "systemctl suspend" my NAS is switching into suspend to ram mode with a power consumention of 3-4 kwh. Some updates ago if i pressed the "Standy" button on the UI, it happend the same as i entered the command. Can anyone help?

    • OMV uses the pm-hibernate, pm-powersave, pm-suspend-hybrid, pm-is-supported and pm-suspend CLI tools to manage the power management. Maybe they work different than systemctl. The internal scripts use pm-is-supported to check which power mode is supported, so i assume that this does not really work well on your system.
      Absolutely no support through PM!

      I must not fear.
      Fear is the mind-killer.
      Fear is the little-death that brings total obliteration.
      I will face my fear.
      I will permit it to pass over me and through me.
      And when it has gone past I will turn the inner eye to see its path.
      Where the fear has gone there will be nothing.
      Only I will remain.

    • Power management is tricky. Maybe a new kernel has broken something.

      Ok, i found the problem. I have installed the Flash memory plugin.
      Install instructions:
      1. Execute the following command: nano /etc/fstab
      2. Add noatime and nodiratime to root options. See before and after example lines:
        BEFORE:UUID=ccd327d4-a1ed-4fd2-b356-3b492c6f6c34 / ext4 errors=remount-ro 0 1AFTER:UUID=ccd327d4-a1ed-4fd2-b356-3b492c6f6c34 / ext4 noatime,nodiratime,errors=remount-ro 0 1
      3. Comment out the swap partition. See before and after example lines (only need to add a # to beginning of the line):
        BEFORE:UUID=a3c989d8-e12b-41d3-b021-098155d6b21b none swap sw 0 0AFTER:#UUID=a3c989d8-e12b-41d3-b021-098155d6b21b none swap sw 0 0
        If i just change the line mentioned in point 2, standby is working, but if i also change the line mentioned in point 3 (deactivating the swap partition) standby is not working anymore. Does anyone know this bug or have any idea how i can solve this?
