It sounds like all you have to do is a
umount /dev/sda2
before you run the command.  But the partition shouldn't have been
mounted in the first place.  It's acting like the skip is actually doing
a mnt/sysimage.

Maybe you'll have to take the /mnt/sysimage route and do a umount on the
partition under /mnt/sysimage.
e.g.  umount /mnt/sysimage/
where /mnt/sysimage is /dev/sda2 because it is the root partition.

These are the things I would try, but I offer no guarantee they will
work.  Perhaps someone else will have more useful advice.
