I have a disk failure in software RAID (1) and marked a broken disk as fault (mdadm --manage /dev/md0 --fail /dev/sda1). Unfortunately I destroyed data on the second disk after that. Is it possible to restore data from disk I marked as failed (/dev/sda1)? If so, how?
UPDATE: OK, I've found the solution, I have to create a new md device: mdadm --assemble /dev/md10 /dev/sda4 --run
After that I had some troubles because of duplicate LVM PVs, but with a little effort I was able to get some data. Not all - because the hard drive is severely damaged...
