forgot to mention that /dev/mapper/Anarres--64--main-root is an XFS file system.  

sorry about the red herrings in my previous email; didn't realize that fsck.xfs
does nothing.  I found xfs_check and xfs_repair, and discovered many inodes with
errors, including (and this is the terrifying bit) the inode for /usr/lib.  So
when I boot into the system, /usr/lib is missing, and anything that resides
there is gone.  xfs_repair says something about "moving to lost+found", but I
don't know really whatthat means.

SO now I wonder:  what can I do to fix this now?  and how could something so
catastrophic happen so easily?  It turns me rather sour on XFS -- this is my
first time trying it out, and I have to say ext3 never gave me problems of this
magnitude, no matter how badthe crash...

I suppose I could try apt-get install --reinstall <everything> but even if that
works I guess all the other missing inodes will stil lbe missing, right?  

anyway, thanks for the help,

Matt
