extendfs_vxfs(1M)extendfs_vxfs(1M)NAME
extendfs_vxfs: extendfs - extend VxFS file system size
SYNOPSIS
size] special
DESCRIPTION
If the VxFS file system image created on special does not use all of
the available space, 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 (see mount(1M)).
The Version 5 disk layout supports file systems up to 32 terabytes.
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 (8 TB)
· 4096 bytes 17,179,868,156 sectors (16 TB)
· 8192 bytes 34,359,736,312 sectors (32 TB)
The Version 6 disk layout supports file systems up to 256 terabytes.
The size to which a Version 6 disk layout file system can be increased
depends on the file system block size:
· 1024 bytes 34,359,736,312 sectors (32 TB)
· 2048 bytes 68,719,472,624 sectors (64 TB)
· 4096 bytes 137,438,945,248 sectors (128 TB)
· 8192 bytes 274,877,890,496 sectors (256 TB)
The maximum file system size supported is 2 terabytes. For a file sys‐
tem's size to be increased to 32 terabytes or greater, the file system
must be on a 64-bit kernel operating system and must reside on a VERI‐
TAS Volume Manager volume.
If the file system resides on a volume set, will fail. Use the
fsvoladm(1M) command to extend a multi-volume file system.
When the file system size is grown with the extendfs command, the
intent log size is not automatically increased.
Options
recognizes the following options:
Specify the VxFS file system type.
Query special to determine the size. The file system is not
extended.
Specify the number of
blocks to add to the file system. If size is omitted,
the maximum possible size is used.
Specify verbose mode, which displays the resulting size of file
system
along with output of the newly sized file system.
Without there is no output.
Operands
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 (see
mount(1M)).
EXAMPLES
This example shows how to increase the capacity of a file system cre‐
ated on a logical volume.
