So far, you can just create a new mirror LV with (e.g.) lvcreate -m1. (needs at least 3 PVs in the VG) Eventually you'll be able to use lvconvert to convert an existing LV into a mirror. Kernel-side improvements are on they way too (device error-handling/read balancing). > whether the ability to attach one lv to another and form a mirror and then split > the mirrored lv into two distinct lvs that are both mountable (similar to a > snapshot only a completely separate lv). We're planning to support that, yes.
