NAME
extendfs - extend a file system size (generic)
SYNOPSIS
/usr/sbin/extendfs
[-F FStype ][-q
][-v][-s size] special
DESCRIPTION
If the original file system image created on special does not make use of all of the available space,
extendfs can be used to increase the capacity of a file system by updating the file system structure to
include the extra space.
The command-line parameter special specifies the device special file of either a logical volume or a disk
partition. The special must be un-mounted before
extendfs
can be run (see mount(1M)).
Options
extendfs recognizes the following options:
-F FStype
Specify the file system type on which to operate (see fstyp (1M) and fs_wrapper (5)). If
this option is not included on the command line, then the file system type is determined
from the file
/etc/default/fs
.
-q Query the size of special . No file system extension will be done.
-v Verbose flag.
-s size Specifies the number of DEV_BSIZE blocks to be added to the file system. If size is not
specified, the maximum possible size is used.
EXAMPLES
To increase the capacity of a file system created on a logical volume, enter:
umount /dev/vg00/lvol1
lvextend -L larger_size /dev/vg00/lvol1
extendfs -F hfs /dev/vg00/rlvol1
mount /dev/vg00/lvol1 mount_directory
