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 informa-
  tion 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.
