    • disk unmounted alone

      Hi,
      I am new to OMV but I succeed in installing and make it work properly.

      then I have installed and mounted a first HDD with no issue.
      after a week, I decided to mount a second HDD and succeed. I have transfered datas on it with no issue.

      a few days later, I discovered an issue with second HDD. my computer could browse the content but when I launch an AVI file, windows told me that the file was missing (on all AVI or MKV of the harddrive).

      so I reboot my OMV machine and then I see in the GUI that the hard drive is not mounted anymore.
      HDD is visible in the disk list but the status is "missing" in the file system.
      If I go on the command line and type "fdisk _l" the hdd is here under /dev/sdc

      it is like the mounted disk dismounted itself and I can't get back.

      please help me, I have done many search but could not find the solution

      I have experienced similar problems with my HC2s and Seagate IronWolf HDDs.

      I figured out that if I modified any the physical disk properties: (Edit on the Disk).

      Advanced Power Management
      Automatic Acoustic Management
      Spindown Time
      Write Cache

      ...then the HDDs would unmount themselves after a short while, and fail to mount on reboot. And a backup system drive SD-card had to be used to recover. I couldn't figure out how to repair the configuration. But I didn't work on it very long.

      Some research seems to indicate that some Seagate HDDs are incompatible with hdparm, which I assume OMV uses? Instead you are supposed to use SeaChest Power Control tools, made by Seagate. Other HDDs may also be incompatible.

      I have not investigated further, my HDDs work fine on default settings, even if they spin down a little too fast for my taste. Less than a minute when idle. I would prefer 10 minutes or so.

      I might try the SeaChest in the future.

      Try reinstalling and don't touch the edit button on the hdd. It might help?

      Hmm this is quite fast, at least for me. My hdd is set to 300 minutes.
      Have you tried setting time(-t 10) in JMS578 firmware? It works in HC1, it may work in HC2...

      No, I haven't. But I might try it. Thanks for that!

      Yes. It should work. I did similar with HC1.
