(see vgcreate(1M)).

One, and only one, -l, -L,or

-m option must be speciﬁed.

-m mirror_copies Set the number of mirror copies allocated for each logical extent. A mirror

copy contains the same data as the original. mirror_copies can have the

value

1 or 2. It must be greater than the current value.

Data in the new copies is synchronized. The synchronization process can be

time consuming, depending on hardware characteristics and the amount of

data.

One, and only one, -l, -L,or

-m option must be speciﬁed.

EXTERNAL INFLUENCES

Environment Variables

LANG determines the language in which messages are displayed.

If LANG is not speciﬁed or is null, it defaults to "C" (see lang(5)).

If any internationalization variable contains an invalid setting, all internationalization variables default to

"C" (see environ(5)).

EXAMPLES

Increase the number of the logical extents of a logical volume to 100:

lvextend -l 100 /dev/vg01/lvol3

Increase the logical volume size to 400 MB:

lvextend -L 400 /dev/vg01/lvol4

Allocate two mirrors (that is, two copies of the original) for each logical extent of a logical volume:

lvextend -m 2 /dev/vg01/lvol5

Mirror a logical volume onto a particular physical volume.

lvextend -m 1 /dev/vg00/lvol3 /dev/dsk/c0t3d0

Increase the size of a ﬁle system existing on a logical volume.

First, increase the size of the logical volume.

lvextend -L 400 /dev/vg06/lvol3

Unmount the file system.

umount /dev/vg06/lvol3

Extend the file system to occupy the entire (larger) logical volume.

extendfs /dev/vg06/rlvol3

Remount the file system.

mount /dev/vg06/lvol3 /mnt
