Can't mount RAID10 "more filesystems detected"

  • Hello folks,

    I upgraded a few days ago from OMV 3.* to OMV 4.
    But now I can't mount anymore my RAID10. Do you have any sugesstions?

    Error of sudo mount /dev/md0 /srv/dev-disk-by-label-Raid10

    sudo mount /dev/md0 /srv/dev-disk-by-label-Raid10
    mount: /dev/md0: more filesystems detected. This should not happen,
    use -t <type> to explicitly specify the filesystem type or
    use wipefs(8) to clean up the device.

    This is the blkid output:

    Should work, shouldn't it?

    Would be awesome to get help!

    Have a good day,
