 NAME
      fsadm - an HFS file system administration command

 SYNOPSIS
      /usr/sbin/fsadm [-F hfs] [-V] [-o specific_options] special

 DESCRIPTION
      The fsadm command is designed to perform selected administration tasks
      on a HFS file systems.  special is a device file containing an
      unmounted file system.

      Only a superuser can invoke fsadm.

    Options
      -F hfs	     Specify the HFS file system type.

      -o specific_options
		     Specify a list of comma separated suboptions and/or
		     keyword/attribute pairs from the list below.  The
		     following specific_options are valid on HFS file
		     systems.

			  largefiles	 Converts a nolargefiles file system
					 to a largefiles file system. The
					 file system should be unmounted and
					 must be in a clean state (see
					 fsck(1M)).  A largefiles file
					 system supports file sizes greater
					 than 2 gigabytes.

			  nolargefiles	 Converts a largefiles file system
					 to a nolargefiles file system. The
					 file system should be umounted and
					 must be in a clean state (see
					 fsck(1M)).  All largefiles should
					 be purged from the file system for
					 the conversion to succeed.

      -V	     Echo the completed command line, but perform no other
		     action.  The command line is generated by incorporating
		     the user-specified options and other information
		     derived from /etc/fstab.  This option allows the user
		     to verify the command line.

 DIAGNOSTICS
      Error and warning messages may originate from fsadm and fsck.  See
      fsadm(1M) or fsck(1M) to interpret the error and warning messages.

 EXAMPLES
      Convert a nolargefiles HFS file system to a largefiles HFS file
      system:

 fsadm_hfs(1M)						       fsadm_hfs(1M)




	   fsadm -F hfs -o largefiles /dev/vg02/rlvol1

      Convert a largefiles HFS file system to a nolargefiles file system:

	   fsadm -F hfs -o nolargefiles /dev/vg02/rlvol1

      Display relevant HFS file system statistics:

	   fsadm -F hfs /dev/vg02/rlvol1

 WARNINGS
      The size of a file system will impact the performance of the fsadm
      command.

      During conversion from largefiles file system to a nolargefiles file
      system fsadm scans the entire file system for a large file. This
      functionality degrades the performance of the fsadm command.

 FILES
      /etc/fstab	       Static information about the systems
