.sh DESCRIPTION
.it Volcopy
makes a literal copy of the filesystem
using
a blocksize matched to the device (10 blocks for tape
.it "[vc10],"
50 blocks for RP03
.it "[vc50],"
or 88 blocks for RP04,5,6
.it "[vc88])."
Using
.it vc10,
a 2400 foot/800 bpi tape will hold
40K blocks; 65K blocks fit at 1600 bpi.
.s3
The
.it fsname 
argument represents the mounted name (e.g.: `root', `u1', etc.)
of the filsystem being copied.
.s3
The
.it "special"
should be the physical disk or tape (e.g.: `/dev/rrp15', `/dev/rmt0', etc.).
.s3
The
.it "volname"
is the physical volume name (e.g.: `pk3', `t0122', etc.)
and should match the external label sticker.
Such label names are limited to five or fewer characters.
.s3
.it "Special1"
and
.it "volname1"
are the device and volume from which the copy of the filesystem is
being extracted.
.it "Special2"
and
.it "volname2"
are the target device and volume.
.s3
.it Fsname
and
.it volname
are recorded in the last 12 characters
of the superblock (char fsname[6], volname[6];).
.s3
.it Labelit
can be used to provide initial labels for unmounted disk
or tape filesystems.
With the optional arguments omitted,
.it labelit
prints current label values.
The
.bd \*-n
option provides for initial labelling of new tapes or disks
(this destroys previous contents).
