Filesystem is gone but Raid5 is clean and displaying used space correctly

  • Hello everyone...

    Thank you so much for sharing your expertise and time helping us all.


    Again a missing filesystem! All clean after rebuilding the array but the ext4 fs is gone (yes I kicked the power cable).

    Individually each disk report fine and the array seems solid but e2fsck -fn /dev/md127 report:


    e2fsck 1.44.5 (15-Dec-2018)

    ext2fs_open2: Bad magic number in super-block


    it happened on OMV4. Raid tested on a OMV5 and same issue.


    mdadm -D /dev/md127 report the correct array size and used size, but I can't mount the filesystem, not even manually on the cli.


    I found online a user that got his data back by executing mkfs.ext4 /dev/md127 but this sounds very wrong to me... what do you think?


    I added some data bellow, if anyone has an idea it would be very appreciated


    Thank you!!!!!

    Leco
