So surely therein lies the problem? - If OnLine "thinks" it sees physically contiguous space which is actually all over the place, all its efforts to do sorted writes, read-ahead and all that are going to result in head thrashing? (Presumably more likely to be a problem with RAID than LVM)? And if you take a set of disks, call them a single partition and then just build a single chunk on it, you're losing all the possible benefits of a true multi-disk strategy - of which the more recent OnLine manuals go to such pains to stress the importance. No, I rest my case: LVM and RAID - don't do it. akent@cix.compulink.co.uk (Andy Kent) -------------------------------------
