'zpool add' will complain if the number of disks aren't equal, forcing you to use -f to get it to work. I wonder why this is? Does this have to do with the way zfs determines what goes where? Does whatever system that is used work better with similar vdevs? > Now some additions may not make sense for what you want to do, but they > are available. I setup a test zfs sytem at work for some of the other non-solaris savvy linux admins and it had a 6x36g raidz, a 6x73g raidz and a 143g mirror. It's not something we pushed hard, so I don't know what the performance impact would be, but it certainly did work. :) Which raises the question..... What are the performance implications of pairing different "types" of vdevs in a single pool? -brian -- "Perl can be fast and elegant as much as J2EE can be fast and elegant.
