lvconvert [-m/--mirrors Mirrors [--corelog] [-R/--regionsize MirrorLogRegionSize]] [-A/--alloc AllocationPolicy] [-h/-?/--help] [-v/--verbose] [--version] LogicalVolume[Path] [PhysicalVolume[Path]...]

lvconvert will change a linear logical volume to a mirror logical volume or vis versa. It is also used to add and remove disk logs from mirror devices.

See lvm for common options. lvm for common options. -->

-m, --mirrors Mirrors
	Specifies the degree of the mirror you wish to create. For example, "-m 1" would convert the original logical volume to a mirror volume with 2-sides; that is, a linear volume plus one copy.
--corelog
	This optional argument tells lvconvert to switch the mirror from using a disk-based (persistent) log to an in-memory log. You may only specify this option when the --mirror argument is the same degree of the mirror you are changing.
-R, --regionsize MirrorLogRegionSize
	A mirror is divided into regions of this size (in MB), and the mirror log uses this granularity to track which regions are in sync.

"lvconvert -m1 vg00/lvol1"
converts the linear logical volume "vg00/lvol1" to a mirror logical volume. This command could also be used to convert a two-way mirror with an in-memory log to a two-way mirror with a disk log.

"lvconvert -m1 --corelog vg00/lvol1"
converts a two-way mirror with a disk log to a two-way mirror with an in-memory log.

"lvconvert -m0 vg00/lvol1"
converts a mirror logical volume to a linear logical volume.
