Subject: Ext2-fs error
Date: Wed, 6 Dec 2000 22:50:43 +0100 (CET)	[thread overview]
Message-ID: <200012062150.WAA01033@john.epistle> (raw)

The EXT2-fs errors I recently reported for test11 seem to be gone with
test12-pre5. At least I couldn't reproduce the error, neither with
overcommit_memory turned on nor off; maybe the error was due to
turning on write cache of my hard disk.

The error was a wrong reading of directory lengths and inode nnumbers:
The file system seemed to read the inode numbers not as supposed to do:
xxxx|xxxx|xxxx|xxxx|xxxx
     rrrr

but like this:
xxxx|xxxx|xxxx|xxxx|xxxx
 rrr_r
The message was:
