Subject: e2fsck doesn't repair broken ext4

Hi,

after a system crash, I had a problem with ext4 that e2fsck didn't fix. I
don't know if e2fsck or ext4 was wrong. In the end, I had to remove the
broken directory, which succeed and solved my problem.

These are the steps I did:

01 % e2fsck -fy /dev/root
02 % dumpe2fsck -x /dev/root
03 % e2image -r /dev/root
04 % apt-get install
05 % dmesg
06 % dumpe2fs -x /dev/root
07 % e2image -r /dev/root
08 % e2fsck -y /dev/root
09 % dumpe2fs -x /dev/root
10 % e2image -r /dev/root
11 % apt-get install
12 % dmesg

I've put the output and images of all these commands at
<http://alioth.debian.org/~jo-guest/ext4/>. I hope they help you somehow.

Regards, Jörg.
