[linux-lvm] lvm raid: pvmove vs lvconvert

[lejeczek]

lvm has fantastic man pages, would be great if "--replace" 
was shortly explained in context of raid0.
Would it work? does it move data?

I don’t think it makes a huge difference which you use, but I would tend to use ‘lvconvert --replace’ when working with RAID segment types.
