[linux-lvm] LVM LV raid5 - can it be extended?

[lejeczek]

hi everybody

I wonder - is it feasible and safe to extend LV raid5?
I'd be trying to add a few more disks which will become PVs 
in their entirety, then use whole PVs to extend LV.

Also if possible interesting would be to know if resyncing 
such an extended LV could be negated by re-creating LV anew 
if it's (resync) faster.
In other words: lvextend raid5 + resync VS lv(re)create 
raid5 resync.

many thanks
