--- Comment #8 from Kirk McKusick <mckusick at FreeBSD.org> ---
This bug falls into the class of bugs that occur when using journalling.
Specifically, the journal only tracks inconsistencies that can occur based on
the order of the write completions to the disk. If the disk lies about write
completions, then the disk will be inconsistent in ways that the journal does
not know. Recovery using journalling is quick, because it only checks the
things that it knows may be wrong. If other errors have occurred, the journal
will not fix them. Running fsck -f ignores the journal and does a full
consistency check of the disk so will find and fix the errors about which the
journal is unaware. When running on lying disks, you should NOT use
journalling. Rather run with just soft updates. After a crash it will take
longer to come back up, but all of the problems will be found and fixed. You
can disable journalling using the command `tunefs -j disable'. When creating
new filesystems, use `newfs -U ...' instead of `newfs -j ...'.
