The "traditional" approach this is to slice the disk yourself so you have a slice size with a known area and a dummy slice of a couple of GB in case a replacement is a bit smaller. Unfortunately, ZFS on Solaris disables the drive cache if you don't give it a complete disk so this approach incurs as significant performance overhead there. FreeBSD leaves the drive cache enabled in either situation. I'm not sure how OI or Linux behave. -- Peter Jeremy
