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 infor‐
       mation 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 spec‐
       ify 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 authoriza‐
       tion to run this command.

       The dumpfs command does not report information on the AdvFS  file  sys‐
       tem.
