NAME
extendfs_vxfs: extendfs — extend VxFS file system size
SYNOPSIS
extendfs
[-F
vxfs]
[-q]
[-v]
[-s
size]
special
DESCRIPTION
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
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
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
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)
4096 bytes 17,179,868,156 sectors sectors (16 TB)
8192 bytes 34,359,736,312 sectors sectors (32 TB)
EXAMPLES
This example shows how
to increase the capacity of
a file system created on a logical volume.
