[linux-lvm] Does LVM2 support mirrored volumes

[David Plainfosse]

Hi,

I am looking for a corresponding Linux LVM2 option of the AIX LVM mklv  that
enables
mirrored copies when creating a Logical Volume 

The mklv AIX option is :

-w MirrorWriteConsistency 
y	Turns on mirror write consistency which insures data consistency
among mirrored copies of a logical volume during normal I/O processing.




I have read in archived emails that the lvcreate  -m1 option enables
mirrored copies but it is not officially
supported. Do you know if a particular LVM2 release support mirrored volumes
?
We plan to use lvm2-2.00.32 release.
