    • How do I mount existing Filesystem / Filesystem wont show up on Webinterface

      I had OMV 3 running for some time and decided to upgrade to OMV4. I've got the new system running und up-to-date. My problem is, i cant mount my existing filesystem via webinterface. I've got a 8TB Hardware RAID as logical Volume (/dev/sda) and it shows up under "Drives":

      However, I'm not able to mount my ext4 filesystem (/dev/sda1) via webinterface:

      I can mount it via shell and access my files:

      I have not added the drive to fstab, since I read that i have to mount it via web interface, otherwise it wouldnt create the necessary database entries.

      Some information about the drive (umounted):



      fdisk -l

      Any help would be greatly appreciate, since I dont know what to do anymore on the webinterface.

      Also, i get those messages, i dont know if that is related:

      Error #0:
      OMV\Exception: Failed to read file '/tmp/bgstatusnw5ooV' (size=0). in /usr/share/php/openmediavault/json/

      Thank you!

    • 1. You should upgrade the system to the lastest version via CLI or UI, then the error "Failed to read file '/tmp/bgstatusnw5ooV' (size=0)" disappears.
      2. It seems that there are problems with filesystems on RAID devices that are created with OMV3/Debian8. As you see blkid can not see the filesystem. That's because OMV can not display it because it rely's on this information. I do not have any workaround for this issue, most people simply copy the data to a second device and recreate the RAID on OMV4/Debian9.

      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.
