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 informa-
     tion for the file system or special device	specified, unless -m is	speci-
     fied.  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.
