NAME
     dumpfs - dump file system information



SYNOPSIS
     dumpfs [filesys | device]

DESCRIPTION
     dumpfs prints out the super block and cylinder group information for the
     file system or special device specified.  The listing is very long and
     detailed.

     dumpfs is useful mostly for finding out certain file system information
     such as the file system block size, minimum free space percentage, and
     the file system level that can be upgraded with the -c option of
     fsck_ffs(8).  All of this information can be found within the first twen-
     ty lines of the output.
