[...] snipped very handy outline Thank you. That kind of walk through is really helpful here. I haven't actually done any of it yet, still cogitating. Also though, for my lightish usage... as home lan NAS I kind of wonder if its worth trying that. It would be nice to make better use of the space I have. But as someone suggested it might be better to get two more bigger drives. 1t or 1.5t would handle all my data on one pair. Then I guess after moving all the data to a single zpool made up of those 2 new disks, I could then add the freed up drives as vdevs to it? So if you have time and inclination another walk through scheme would be well appreciated. I think, I'd just leave rpool clear out of it. That mirror is made of 2 500gb IDE drives, that are now almost outdated by the move to sata. rpool consists of 2 500gb IDE drives. z2 consists of 2 500gb sata drives z3 consists of 2 750 gb sata drives. So I guess I'd add 2 1.5tb sata drives and create z1 of them. I think I might know how to migrate all the data or at least I'm confident with a little reading of opensolaris docs I will be able to do it. I'm not clear how I'd go about adding the freed up drives to z1. ending up with 3vdevs in z1, each a 2disk mirrors. Or what commands then will stripe(?) the data across them all. Once done, I would then have some thing close to 2.7TB available on z1. I'm wondering if after completing the above migrations, I'd then need to migrate whatever data is now being kept on rpool, onto the new z1 and just leave those 2 rpool disks for the OS, even though it would waste a few hundred GB. But maybe keeping the periodic hefty delete/write off the system disks is worth it? Or would there really be any good reason not to just leave some data on rpool? Maybe certain kinds of data that don't grow to speak of. Is it really that bad having some data stored on the OS (rpool) drives? I'm thinking maybe keeping system (C drive) disk images of the windows lan machines there, which would mean periodic hefty deletes/writes but the amount of data would not really grow too much. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
