 NAME    [Toc]    [Back]
      fs_wrapper - configuration and binary files used by file system
      administration commands

 SYNOPSIS    [Toc]    [Back]
      extendfs [-F FStype] ...

      ff [-F FStype] ...

      fsck [-F FStype] ...

      fsdb [-F FStype] ...

      labelit [-F FStype] ...

      mkfs [-F FStype] ...

      mount [-F FStype] ...

      ncheck [-F FStype] ...

      newfs [-F FStype] ...

      quot [-F FStype] ...

      quotacheck [-F FStype] ...

      volcopy [-F FStype] ...

 DESCRIPTION    [Toc]    [Back]
      The commands listed in the SYNOPSIS can operate on different types of
      file systems.  Each command (except for mount) reads file system
      specific configuration files that control the command's behavior, and
      invokes a file system specific binary file to do the actual work.
      FStype is the file system type as optionally specified on the command
      line.  If FStype is not given, then the file system type is determined
      from /etc/fstab by matching an entry in this file with a device
      special provided with the command (see individual commands for details
      of usage).

      Administrators may also define a default file system type for the
      above commands via the file /etc/default/fs.  If this file exists, and
      contains the line:

           LOCAL=FStype

      (e.g., LOCAL=hfs), then the above commands will assume the FStype
      given in /etc/default/fs, unless an FStype is provided on the command
      line or is in /etc/fstab.  The default file system specification is
      provided to maintain compatibility with pre-10.0 invocations of the
      commands.

 WARNINGS    [Toc]    [Back]
      The configuration files /sbin/lib/mfsconfig.d/FStype are supplied by
      HP or by other file system vendors.  They are not meant to be edited
      by System Administrators.  Corruption or removal of these files may
      lead to strange behavior, including the inability to boot.

      The format of the configuration file is subject to change.

      The file system specific binary files are not normally executed
      directly.  However, if the configuration files become unusable, direct
      execution of these binary files may be a useful step in repairing and
      running the system again.  The binary files accept the same arguments
      as the commands by which they are executed.

      The mount command is a special case.  This command currently does not
      read a configuration file, and does not execute a file system specific
      binary file if FStype is cdfs, hfs, nfs, or lofs.  The binary that
      handles these FStypes also processes other FStypes and calls the file
      system specific command if appropriate.

      For historical reasons, the hfs binary files also handle nfs and cdfs,
      so there are no separate binary files for the latter two file systems.

      The commands (except mount) will not work if they are renamed, because
      they are symbolically linked to a single executable
      (/sbin/fs_wrapper).
