I had a mountable fs (pretty sure it was ext3), fsck.ext4 was run with -y and ended in a segmentation fault. Now it is unmountable (dmesg says it's corrupt) and identifies as a ext4 fs via the "blkid" command. The fs happens to sit on a raid 0 array mad up of 3 partitions.
As I am not 100% positive that is was originally ext3 I don't want to try running fsck.ext3. I also have no idea if that would work even if it was the case.
I would hope that fsck is intelligent enough to check the fs type and at least provide a warning.
Any suggestions on how to recover from this would be greatly appreciated.
