Re: [linux-lvm] Mirror Capabilities on LVM2



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).

We're planning to support that, yes.
