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

NAME
     dumpfs -- dump UFS 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, a newfs(8) command is printed that can be used to
     generate a new file system with equivalent settings.

SEE ALSO

HISTORY
     The dumpfs utility appeared in 4.2BSD.
