So admin can erase them anytime he wants to - but in that case it's probabl= y=20 more clever to disable archiving in lvm.conf ;) as archiving eats some CPU.= .. lvm2 itself does *only* care about metadata stored in the 'metadata' area i= n=20 PV header - where there is also ring-buffer which typically keeps pretty lo= ng=20 history of all metadata modifications - this buffer has these days ~1MiB in= =20 size. So unless your metadata are pretty big - the history can be relativel= y=20 easily extracted also out from this place for i.e. recovery purpose. I must admit I don't understand the 'make sure' part of your question?? Are you aiming at some particular issue ?? Regards Zdenek
