Hi!

Unfortunately it won't let me mount (presumably
because its marked dirty).  It says 

mount: wrong fs type, bad option, bad superblock on
/dev/vg0/lvol0, or too many mounted filesystems

(I've had this message before, for example when the
computer was shut down without unmounting because of a
crash, and after running fsck it would go ahead and
mount)

Any ideas?
