DUMPFS(8)               FreeBSD System Manager's Manual              DUMPFS(8)

NAME
     dumpfs - dump file system information

SYNOPSIS
     dumpfs [-m] filesys | device

DESCRIPTION
     The dumpfs utility prints out the super block and cylinder group
     information for the file system or special device specified, unless -m is
     specified.  The listing is very long and detailed.  This command is
     useful mostly for finding out certain file system information such as the
     file system block size and minimum free space percentage.

     If -m is specified, the file system is marshalled in terms of a newfs(8)
     command to generate the file system.

SEE ALSO
     disktab(5), fs(5), disklabel(8), fsck(8), newfs(8), tunefs(8)

HISTORY
     The dumpfs utility appeared in 4.2BSD.

FreeBSD 11.0-PRERELEASE        January 19, 2003        FreeBSD 11.0-PRERELEASE
