    Missed the hardware raid part. I suppose it is raid on a motherboard?

    You will have to try to fix it with the p212 bios. There is really nothing you can do to fix it from OMV.

  • so, after spending a lot of time to search for a solution I found a way:


    after fsck.ext4 -v /dev/sdb1 the output was:



    with mke2fs -n /dev/sdb I searched for superblock backups. The output was:



    With e2fsck -b 294912 /dev/sdb1  (the first 4 superblocks don't work) I repaired my bad superblock. The output was:



    Now I have the problem my Raid10 is mounted as a USB Media. A look in /media/usb/ now I find my data and folders again (Thank god). How can I correct it?

    My fstab look like this:



    is it right if I delete line
     [color=#FF0000][/color]/dev/sdb1 /media/usb0 auto rw,user,noauto 0 0[color=#FF0000] [/color]


    and put a new line at the end like this:


    UUID="2ee5aa4b-5279-4ac9-ba47-b89982c40585 /media/UUID="2ee5aa4b-5279-4ac9-ba47-b89982c40585 ext4 defaults,nofail,acl,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 0 2


    Sorry for my English.


    EDIT: I did it and it is runs properly.
