     dumpfs [filesys | device]

DESCRIPTION    [Toc]    [Back]

     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 twenty
 lines of the output.
