dcopy(1M)
dcopy --
copy filesystems for optimal access time (generic)
Synopsis
dcopy [-F FSType]
[-V] [current_options]
[-o specific_options]
inputfs outputfs
Description
dcopy
copies filesystem
inputfs
to
outputfs.
inputfs
is the device file for the existing filesystem;
outputfs
is the device file to hold the reorganized result.
For the most effective optimization
inputfs
should be the raw device and
outputfs
should be the block device.
Both
inputfs
and
outputfs
should be unmounted filesystems.
current_options
are options supported by the s5-specific module of dcopy.
Other FSTypes do not necessarily support these options.
specific_options indicate suboptions specified in a comma-separated
list of suboptions and/or keyword-attribute pairs for interpretation by
the FSType-specific module of the command.
Command options
-F-
Specify the FSType on which to operate.
If -F FSType is not specified
it is determined by matching the inputfs
(device) with an entry in /etc/vfstab.
If this fails, heuristics similiar to those used
by
fstyp(1M)
are used to determine the file
system type.
NOTE:
If the FSType is known beforehand, use the
-F option. This command executes faster
if it is not required to autodetect file system types.
-V-
Echo the complete command line,
but do not execute the command.
The command line is generated by using
the options and arguments provided by the user
and adding to them information
derived from /etc/vfstab.
This option should be used to
verify and validate the command line.
-o-
Specify FSType-specific options.
Files
/etc/vfstab list of default parameters for each filesystem-
