Thanks for the reply. I would intend to do it offline. Not sure what you mean by dd in a shell. Could you elaborate? Do you mean, make a backup, drop and recreate the pv, vg, lv, and filesystems, and recover backup? I was hoping not to have to do this, kinda defeats the purpose. I was trying to get away with managing all of my filesystems within lvm as LV's, trying to keep the pv's as simple as possible. William T.

I can't immediately think that it would be hugely difficult, but it's a piece of work :-) as for offline, you could do that in an afternoon with shell and dd :-) Other possible strategies include, having partitioned your raid in the first place (yes I know this is silly, but you can see what I mean), or perhaps converting to some other VM software that can do what you need (like, will EVMS do this??) Perhaps there is a way to emulate the 'having partitioned first strategy' and make the new 200G addressable as a seperate block device, at which point a pvmerge command would come in handy :-) (of course that would be easier if the PEs were PE size aligned to the underlying device, but you could take account of that in where you started your new PV :-) Or perhaps some kind soul will point you to something I have missed. Good Luck.
