It's important that you know the difference between "add" and "attach" methods for increasing this size... If you "add" another mirror, then you'll have mirror-0, mirror-1, and mirror-2. You cannot remove any of the existing devices. If you "attach" a larger disk to mirror-0, and possibly fiddle with the autoexpand property and a little bit of additional futzing (pretty basic, including resilver & detach the old devices) then you can effectively replace the existing devices with larger devices. No need to consume extra disk bays. It's all a matter of which is the more desirable outcome for you. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
