NAME
  dumpfs - Dump UFS file system information

SYNOPSIS
  /usr/sbin/dumpfs  filesystem... | device

DESCRIPTION
  The dumpfs command prints out the super block and cylinder group
  information for the specified UFS file system(s) or special device. The
  listing is very long and detailed.  This command is useful for getting
  information about the file system block size and minimum free space
  percentage, for example.  If the file system is mounted, you must specify
  the raw device.  The following is an example of device entries in an
  /etc/fstab file:

       /dev/disk/dsk8a	 /	 ufs  rw  1 1
       /dev/disk/dsk8g	 /	 ufs  rw  1 2
       /dev/disk/dsk8b	 /	 ufs  sw  1 2

  To see the information on the /usr file system (which is mounted), enter
  the following command:

  dumpfs /dev/rdisk/dsk8g You must have the sysadmin command authorization to
  run this command.

  The dumpfs command does not report information on the AdvFS file system.
