dcopy(8)
NAME
dcopy − copy file systems for optimal access time
SYNTAX
/etc/dcopy [options] inputfs outputfs
DESCRIPTION
The dcopy command copies file system inputfs to outputfs. The existing file system is inputfs; 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. The dcopy command must be run on unmounted file systems and in the case of the root file system, copied 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(8). The dcopy command 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.
The dcopy command 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. The dcopy command also attempts to modify its command line arguments so its progress can be monitored with ps(1).
