You can use ccd(4) or raid(4) to aggregate these two disks as one
logical lump of storage.  (Personally, I suggest using RAID with
the drives set to autoconfigure.)

Having said that, the result is not quite the same as having a logical
volume manager, which is the thing I most miss from NetBSD having
previously enjoyed AdvFS on Digital Unix (and currently vinum+growfs
on FreeBSD).  For example, ccd(4) and raid(4) do not allow you to
"grow" existing volumes by later adding new disks, unlike a logical
volume manager.

Does anyone know if there is anyone working on a LVM for NetBSD??

Paul.
