dcopy_s5(1M)
dcopy_s5 --
copy s5 file systems for optimal access time
Synopsis
dcopy [-F s5] [generic_options]
[-sX] [-an]
[-d] [-v]
[-ffsize[:isize]] inputfs outputfs
Description
generic_options
are options supported by the generic dcopy command.
With no options,
dcopy
copies files from
inputfs
compressing directories by removing vacant entries, and spacing consecutive
blocks in a file by the optimal rotational gap.
s5-specific options
-F s5-
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.
-sX-
Supply device information for creating an optimal
organization of blocks in a file.
X
must be of the form cylinder_size:gap_size.
-an-
Place the files not accessed in
n
days after the free blocks of the
destination file system
If no
n
is specified then no movement occurs.
-d-
Leave order of directory entries as is.
The default is to sort the directory based on how recently each
entry has been accessed.
Entries accessed within the last 24 hours are placed at the
beginning of the directory.
All subdirectories are treated as if they were accessed within the
last 24 hours.
-v-
Reports how many files were processed and how big
the source and destination freelists are.
-f fsize[:isize]-
Specify the
outputfs
file system (fsize) and inode list (isize) sizes in logical blocks.
If the suboption (or :isize)
is not given, the values from
inputfs
are used.
dcopy
catches interrupts and quits and reports on its progress.
To terminate
dcopy,
send a quit signal followed by an
interrupt or quit.
Files
/etc/mnttab list of file systems currently mounted

fsck should be run on the new file system
created by dcopy before it is mounted.
