File Systems not showing mounted status for btrfs

    • OMV 5.x (beta)
    • File Systems not showing mounted status for btrfs

      Hi,

      on File Systems tab (OMV 5.0.14-1) I see my btrfs file system, raid5 with 3 disks, but it says "N/a" for size, used and available.
      Mounted says no, Referenced yes.
      Mount button is clickable and mounts fs correctly, but File Systems tab stays unchanged.

      when I created new 2 disk btrfs fielsystem by hand it showed all data ok, after I've added 3rd disk (sdc1) it stopped.

      btrfs shows devid 1 for sdc1, so it comes at first place and shows also in mount as device.
      OMV File Systems tab shows sda4 in first place - maybe this is problem and OMV can't match?

      hope for help :)
