extendfs(1M)

NAME

extendfs (generic) − extend a file system size

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
