NAME

extendfs − extend file system size

SYNOPSIS

/etc/extendfs [-q] [-v] [-s size] special

DESCRIPTION

If the original hfs filesystem image created on special does not make use of all of the available space, extendfs can be used to increase the capacity of an hfs filesystem by updating the filesystem structure to include the extra space. 

The command-line parameter special specifies the character device special file of either a logical volume or a disk partition.  If special refers to a mounted filesystem, special must be un-mounted before extendfs can be run (see mount(1M)).

Options

extendfs recognizes the following options:

-q Query the size of special. No file system extension will be done.

-v Verbose flag. 

-ssize Specifies the number of DEV_BSIZE blocks to be added to the file system.  If -ssize is not specified, the maximum possible size is used. 

EXTERNAL INFLUENCES

Environment Variables

LANG determines the language in which messages are displayed. 

If LANG is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of LANG. 

If any internationalization variable contains an invalid setting, lvchange behaves as if all internationalization variables are set to "C".  See environ(5).

EXAMPLES

To increase the capacity of a filesystem created on a logical volume, enter:

umount /dev/vg00/lvol1

lvextend -L larger_size /dev/vg00/lvol1

extendfs /dev/vg00/rlvol1

mount /dev/vg00/lvol1 mount_directory

WARNINGS

The root filesystem cannot be extended using the extendfs command because the root filesystem is always mounted, and extendfs only works on unmounted filesystems. 

RETURN VALUE

extendfs returns the following values:

 0 No errors were detected and filesystem was successfully extended. 

 1 Command aborted. 

REMARKS

In order to extend a filesystem to the 4-Gbyte maximum filesystem size, enough Cylinder Group summary blocks must be reserved by mkfs (see mkfs(1M)). For a filesystem created by an older version of mkfs (prior to HP-UX Release 9.0 — see mkfs(1M)), the full 4-Gbyte filesystem capacity may not be achievable by use of extendfs.
