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
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)
Hewlett-Packard Company - 1 - HP-UX 11i Version 2: August 2003
+ 4096 bytes 17,179,868,156 sectors sectors (16 TB)
+ 8192 bytes 34,359,736,312 sectors sectors (32 TB)
EXAMPLES [Toc] [Back]
This example shows how to increase the capacity of a file system
created on a logical volume.
