DCOPY(1M)
NAME
dcopy − copy file systems for optimal access time
SYNOPSIS
/etc/dcopy [options] inputfs outputfs
DESCRIPTION
Dcopy copies file system inputfs to outputfs. Inputfs is the existing file system; outputfs is an appropriately sized file system, to hold the reorganized result. Inputfs must be the raw device and outputfs must be the block device. Dcopy must be run on unmounted file systems (in the case of the root file system, copy to a new pack). With no arguments, dcopy copies files from inputfs compressing directories by removing vacant entries, and spacing consecutive blocks in a file by the optimal rotational gap.
Options:
−sX 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 fsck(1M). Dcopy will attempt to use the values from the output filesystem if the parameters given in this option are not reasonable.
−an place the files not accessed in n days after the free blocks of the destination file system (default for n is 7). If no a is specified then no movement occurs.
−d leave order of directory entries as is (default is to move sub-directories to the beginning of directories).
−v currently reports how many files were processed, and how big the source and destination freelists are.
−n do not ask before copying file systems. Default is to ask for confirmation before proceeding.
−ffsize[:isize]
specify the outputfs file system and inode list sizes (in blocks). If not given, the values from the outputfs are used.
Dcopy catches interrupts and quits and reports on its progress. To terminate dcopy, send a quit signal and dcopy will no longer catch interrupts or quits. Dcopy also attempts to modify its command line arguments so its progress can be monitored with ps(1).
