dcopy(1M)
dcopy (generic) --
copy file systems for optimal access time
Synopsis
dcopy [-F FSType]
[-V] [current_options]
[-o specific_options]
inputfs outputfs
Description
dcopy
copies file system
inputfs
to
outputfs.
inputfs
is the device file for the existing file system;
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 file systems.
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.
The FSType should
either be specified here or be determinable from /etc/vfstab
by matching the inputfs (device) with an entry in the table.
- -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 file system
