LVM supports mirroring or raid1.<br>
So to create a raid1 you would do something like "lvcreate -n
raidvol -L 1T --mirrors 1 /dev/bigvg"<br>
You can add a mirror to an existing logical volume using lvconvert
with something like "lvconvert --mirrors +1 bigvg/unmirroredlv"<br>
<br>
But other than simple mirroring you will need mdadm.<br>
