[SOLVED] [mdadm] rescue superblock
I had a raid0 array (4x 1 To) made with mdadm. Everythings worked but one disk controller stopping working yesterday.
When I tried to rebuild my array, strangly, one of my disk was reconized as "spare disk".
I'm pretty sur that my data on disks are okay, and it's an ext4 partition on it.
The problem is, I searched on Google to find how to correct that, and a solution was to create again the array. Well I tried:
# mdadm --create -v -l 0 -n 4 /dev/sde1 /dev/sdf1 /dev/sdg1 /dev/sdh1
mdadm say me that drives was already on a array, I continue anyway... Well, md0 is now created... but I cannot mount my partition.
(fsck don't find any ext partition on drive too)
Now I think that my superblock are overwritten on my disk... Is there anyway to rescue them ?
Note: I cannot copy/past old informations about disks...
