I had a rather large ext4 partition on an Areca RAID shut down uncleanly while it was writing. When I mount it again, it recommends fsck, which I
do, and I get the following error:
Failed to optimize directory … EXT2 directory corrupted
This error shows up every time I run fsck.ext4 on this partition.
How can I fix this? The file system seems to work ok otherwise, I can mount it and it doesn’t complain, using it looks like it’s ok, etc.
