fsadm

fsadm(1M)																 fsadm(1M)

NAME

       fsadm - a file system administration command

SYNOPSIS

       FStype] specific_options] special

DESCRIPTION

       The  command  is designed to perform selected administration tasks on file systems. These tasks may differ between file system types.  spe-
       cial is a device file containing an unmounted file system. However, if the file system is of the type that provides  online  administration
       capabilities the special could be a directory.  directory must be the root of a mounted file system.

       Only a superuser can invoke

   Options
       Specify the file system type on which to operate (see
		      fstyp(1M)  and  fs_wrapper(5)).  If this option is not included on the command line, then the file system type is determined
		      from the file by matching each special with an entry in that file.  If there is no entry in then the  file  system  type	is
		      determined from the file

       Specify options specific to each file system type.
		      specific_options	is a list of comma separated suboptions and/or keyword/attribute pairs intended for a specific FStype-spe-
		      cific module of the command.  See the file system specific manual entries for a description  of  the  specific_options  sup-
		      ported, if any.

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