Cleaning my /usr/lost+found



Howdy all!

Recently I attempted to install some .deb's when I received error
messages that /usr was mounted read-only.  I know that this *is*
the desired state for /use, and will be once my system settles into
a pattern where I'm not always installing/de-installing packages.
In other words...RSN...

Anyway, a brief look around showed that /usr had some low-level
errors from the WD Caviar drive (again?).  I dropped down to
single user mode and unmounted the drive.  Running fsck on the
partition yielded many errors and a lot of cruft in /usr/lost+found.

Here's what's in /usr/lost+found/   (I promise to only print this list once.)

> cd /usr/lost+found/
> ls -l

Ok.  I like a good challenge, but this is ridicules!!  As I haven't been able
to do anything with these entries.  I have noticed that the file "names" are
actually inode numbers - fsck *did* call them unlinked inodes...

Here's a (brief) synopsis of what I've tried:

> rm *
rm: cannot unlink `#85683': Operation not permitted
rm: remove write-protected file `#85688'? y
rm: cannot unlink `#85688': Operation not permitted
rm: remove write-protected file `#85731'? y
rm: cannot unlink `#85731': Operation not permitted
rm: cannot unlink `#85798': Operation not permitted
rm: remove write-protected file `#85803'? y
rm: cannot unlink `#85803': Operation not permitted
[...]

I *know* that I could wipe out /usr and re-install all of my packages,
but that seems a little drastic.  I've toyed around _very_ _carefully_
with lde and even tried using it to nix /usr/lost+found...next fsck
caught the files and put them back (+1...I'm assuming it was the original
/usr/lost+found/ entry...)

Suggestions!?
Chuck
