     In preen mode, after pass 1 completes, all remaining file systems are

What does fsck consider a "disk drive" in the following setup?

[joan at iaeste-catalunya:~]0 $sudo vinum ld

Still on the fsck man page, what determines "bgfsck availability" as
refered here?

                                                  If background checking is
     available, fsck is invoked twice.  It is first invoked at the traditional
     time, before the file systems are mounted, with the -F flag to do check-
     ing on all the file systems that cannot do background checking.
