Re: Bad directories appearing in ext3 after upgrade 2.4.16 -> 2.4.18+cvs



I forgot to add...

I thought to use debugfs to "dump" a couple of directories that cause
the errors.

In each case there was a single 4096 byte block which "od -c" displays
as:

0000000   8   5   7   2  \n  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
0000020  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
*
0010000

in one case and

0000000   /   d   e   v   /   p   t   s   /   2  \n  \0  \0  \0  \0  \0
0000020  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
*
0010000

in the other.


The newline on the end has me stumped (not that I can particularly
explain the rest).

I will see if any more appear over night, and then boot back to
2.4.17-pre2+

I should also add that this machine is an NFS fileserver, and the
2.4.18 kernel that I was using had some enhancements like reduction of
BKL usage in NFSd, so it's possible that the problem is not in
ext3...  I will review the BKL stuff again tomorrow.
