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.
umount /dev/vg00/lvol1
lvextend -L larger_size /dev/vg00/lvol1
extendfs -F vxfs /dev/vg00/rlvol1
mount /dev/vg00/lvol1 mount_directory
