Wait a minute.  This shouldn't be necessary at all -- at least in
system V.  Bring the system down into single user and then run fsck on
the Block Device for root (not the char device).  For example:

fsck /dev/dsk/0s1

Since one can't unmount root while one is running from it, it makes
sense that one should be able to fsck it while you one is running on
it.  The alternative is to boot from some other media (another disk, a
tape, etc) and *then* run fsck on either the blocked or raw root
partition.
