Lost software RAID 1 file system (ext4)
Posted: Sat May 09, 2020 8:07 pm
Hi,
I am desperately looking for a help to recover a partition and its file system (ext4). I have 2 identical HDDs (1 TB, each) mounted as RAID 1 (software).
Accidentally, I ran mdadm --create /dev/md2 --level=raid1 --raid-devices=2 /dev/sda2 /dev/sdb2 over an existing RAID 1 (Ext4 file system). After that I cannot mount /dev/md2 (even /dev/sda2 nor /dev/sdb2). It results in: "mount: wrong fs type, bad option, bad superblock on /dev/md2, missing codepage or helper program, or other error".
I made a clone of /dev/sda2 to a third HDD and I tried dumpe2fs and fsck, but here are not valid superblocks (I tried all superblock found by dumpe2fs) and they did not able to repair the file system.
As I could not able to mount the partition I believe that the data are still there. Is there any way to revert what I have done, repair the file system, or recover files?
Thank you.
