Hej Mark,

i made a dump of the partition.

Now we try:

dumpe2fs  /dev/md126 | grep -i superblock

fsck -b 8193 /dev/md126

fsck will confirmation of every inode to change the i_block
there are a lot to confirm.

are we on the right way?

the boot system is on a raid1 raidset

No. Cat /proc/mdstat, I think it is. And use smartctl -t
