extendfs_vxfs(1M)                                         extendfs_vxfs(1M)




 NAME    [Toc]    [Back]
      extendfs_vxfs: extendfs - extend VxFS file system size

 SYNOPSIS    [Toc]    [Back]
      extendfs [-F vxfs] [-q] [-v] [-s size] special

 DESCRIPTION    [Toc]    [Back]
      If the VxFS file system image created on special does not use all of
      the available space, extendfs increases the capacity of a VxFS file
      system by updating the file system structure to include the extra
      space.

      special specifies the device special file of either a logical volume
      or a disk partition.  If special refers to a mounted file system, you
      must unmount special before running extendfs (see mount(1M)).

    Options    [Toc]    [Back]
      extendfs recognizes the following options:

           -F vxfs   Specify the VxFS file system type.

           -q        Query special to determine the size.  The file system
                     is not extended.

           -s size   Specify the number of DEV_BSIZE blocks to add to the
                     file system.  If size is omitted, the maximum possible
                     size is used.

           -v        Specify verbose mode, which displays the resulting size
                     of file system along with fsck output of the newly
                     sized file system.  Without -v there is no output.

    Operands    [Toc]    [Back]
      extendfs recognizes the following operand:

           special   The device special file of either a logical volume or a
                     disk partition.  If special refers to a mounted file
                     system, you must unmount special before running
                     extendfs (see mount(1M)).

    Notes    [Toc]    [Back]
      The Version 5 disk layout supports file systems up to 32 terabytes.
      For you to increase a file system to 32 terabytes, it must be on a
      64-bit kernel operating system and must reside on a VERITAS Volume
      Manager volume.  The size to which a Version 5 disk layout file system
      can be increased depends on the file system block size:

           +  1024 bytes  4,294,967,039 sectors (4 TB)

           +  2048 bytes  8,589,934,078 sectors sectors (8 TB)

 EXAMPLES    [Toc]    [Back]
      This example shows how to increase the capacity of a file system
      created on a logical volume.

           umount /dev/vg00/lvol1

           lvextend -L larger_size /dev/vg00/lvol1

           extendfs -F vxfs /dev/vg00/rlvol1

           mount /dev/vg00/lvol1 mount_directory
