 extendfs(1M)                  Series 800 Only                  extendfs(1M)





 NAME
      extendfs - extend file system size

 SYNOPSIS
      /etc/extendfs [-q] [-v] [-s size] special

 DESCRIPTION
      If the original hfs filesystem image created on special does not make
      use of all of the available space, extendfs can be used to increase
      the capacity of an hfs filesystem by updating the filesystem structure
      to include the extra space.

      The command-line parameter special specifies the character device
      special file of either a logical volume or a disk partition. If
      special refers to a mounted filesystem, special must be un-mounted
      before extendfs can be run (see mount(1M)).

    Options
      extendfs recognizes the following options:

           -q        Query the size of special.  No file system extension
                     will be done.

           -v        Verbose flag.

           -ssize    Specifies the number of DEV_BSIZE blocks to be added to
                     the file system.  If -ssize is not specified, the
                     maximum possible size is used.

 EXTERNAL INFLUENCES
    Environment Variables
      LANG determines the language in which messages are displayed.

      If LANG is not specified or is set to the empty string, a default of
      "C" (see lang(5)) is used instead of LANG.

      If any internationalization variable contains an invalid setting,
      lvchange behaves as if all internationalization variables are set to
      "C".  See environ(5).

 EXAMPLES
      To increase the capacity of a filesystem created on a logical volume,
      enter:

           umount /dev/vg00/lvol1

           lvextend -L larger_size /dev/vg00/lvol1

           extendfs /dev/vg00/rlvol1

 extendfs(1M)                  Series 800 Only                  extendfs(1M)





           mount /dev/vg00/lvol1 mount_directory

 WARNINGS
      The root filesystem cannot be extended using the extendfs command
      because the root filesystem is always mounted, and extendfs only works
      on unmounted filesystems.

 RETURN VALUE
      extendfs returns the following values:

            0   No errors were detected and filesystem was successfully
                extended.

            1   Command aborted.

 REMARKS
      In order to extend a filesystem to the 4-Gbyte maximum filesystem
      size, enough Cylinder Group summary blocks must be reserved by mkfs
      (see mkfs(1M)).  For a filesystem created by an older version of mkfs
      (prior to HP-UX Release 9.0 - see mkfs(1M)), the full 4-Gbyte
      filesystem capacity may not be achievable by use of extendfs.
