hi there

in lvm raid LVs, which one should be used and how do they
differ - would you know? Are they meant for different things?

many thanks, L.

sorry, I'm thinking specifically of: lvconvert --replace VS
pvmove

You could use either, I suppose. The replace will pull out the RAID member and replace it with a new one. pvmove will create a temporary mirror for the member being moved. 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.

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