Thanks for your post. I think I understand what you are saying but I don't know how to actually do most of that. If I am going to make a new install of Solaris 10 does it give me the option to slice and dice my disks and to issue zpool commands? Until now I have only used Solaris on Intel with boxes and used both complete drives as a mirror. Can you please tell me what are the steps to do your suggestion? I imagine I can slice the drives in the installer and then setup a 4 way root mirror (stupid but as you say not much choice) on the 13G section. Or maybe one root mirror on two slices and then have 13G aux storage left to mirror for something like /var/spool? What would you recommend? I didn't understand what you suggested about appending a 13G mirror to tank. Would that be something like RAID10 without actually being RAID10 so I could still boot from it? How would the system use it? In this setup that will install everything on the root mirror so I will have to move things around later? Like /var and /usr or whatever I don't want on the root mirror? And then I just make a RAID10 like Jim was saying with the other 4x60 slices? How should I move mountpoints that aren't separate ZFS filesystems? > The only conclusion you can draw from that is: First take it as a given > that you can't boot from a raidz volume.

So RAID10 sounds like the only reasonable choice since there are an even number of slices, I mean is RAIDZ1 even possible with 4 slices? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
