NAME
volcopy, labelit - copy a file system with label checking
SYNOPSIS
[options] fsname special1 volname1 special2 volname2
[options] special [fsname volume
DESCRIPTION
The command makes a literal copy of the file system using a block size matched to the device.
Options
recognizes the following options:
Specify the file system type on which to operate (see
fstyp(1M) and fs_wrapper(5)). If this option is not included on the command line, then the file system type is
determined from the file by matching special with an entry in that file. If there is no entry in then the file sys-
tem type is determined from the file
Invoke a verification sequence
requiring a positive operator response instead of the standard delay before the copy is made.
Specify options specific to the file system type.
specific_options is a list of suboptions and/or keyword/attribute pairs intended for an FStype-specific module of the
command. See the file system specific manual entries for a description of the specific_options that are supported,
if any.
(default) Invoke the DEL-if-wrong verification sequence.
Assume a response to all questions
Echo the completed command line, but perform no other actions.
The command line is generated by incorporating the user-specified options and arguments with other information
derived from This option allows the user to verify the command line.
Other options are used with 9-track magnetic tapes:
Bits per inch.
Size of reel in feet.
Beginning reel number for a restarted copy.
Use double buffered I/O.
The command requests length and density information if they are not given on the command line and they are not recorded on an input tape
label. If the file system is too large to fit on one reel, the command prompts for additional reels. Labels of all reels are checked.
Tapes can be mounted alternately on two or more drives. If the command is interrupted, it asks if the user wants to quit or wants to
escape to the command interpreter. In the latter case, other operations (such as executing the command) can be performed before returning
to the command by exiting the command interpreter.
fsname The file system name on the device (e.g., being copied.
special The physical disk section or tape (e.g., or
volname The physical volume name; it should match the external sticker. Such label names are limited to six or fewer characters. The
argument volname can be to use the existing volume name.
special1 The device from which the copy of the file system is being extracted.
volname1 The volume from which the copy of the file system is being extracted.
special2 The target device.
volname2 The target volume.
The command can be used to provide initial labels for unmounted disk or tape file systems. With the optional arguments omitted, the com-
mand prints current label values. The option provides for initial labeling of new tapes only (this destroys previous contents). The and
options can be specified for the command. The behavior of the and options is similar to their behavior in the command.
FILES
File that specifies the default file system type.
Static information about the file systems.
