copy UNIX filesystems for optimal access time
/etc/dcopy [ -sX ]
[ -an ] [ -d ]
[ -v ] [ -ffsize
[ :isize ]]
The dcopy command copies filesystem
inputfs to outputfs.
is the device file for the existing file system;
is the device file to hold the reorganized result.
This utility is for UNIX filesystems only.
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.
With no options, dcopy copies files from
compressing directories by removing vacant entries, and spacing consecutive
blocks in a file by the optimal rotational gap.
The possible options are:
catches interrupts and quits, and reports on its progress.
To terminate dcopy send a quit signal,
followed by an interrupt or quit.
supply device information for creating an optimal
organization of blocks in a file.
The forms of X are the same as the
-s option of
place the files not accessed in n
days after the free blocks of the
destination file system
(default for n is 7).
If no n is specified, then no movement occurs.
leave order of directory entries as is
(default is to move sub-directories to the beginning of directories).
currently reports how many files were processed, and how big
the source and destination freelists are.
-ffsize [ :isize ]
specify the outputfs
file system and inode list sizes (in blocks).
If the option (or :isize)
is not given, the values from the
inputfs are used.
also attempts to modify its command line arguments so its
progress can be monitored with
Do not use dcopy on AFS or EAFS
filesystems (dcopy will corrupt such filesystems).
Use dcopy with UNIX (S51K) filesystems only.
