I've just done this procedure on a test server, just so I know what I'm playing with when the time comes. I've replaced all 3 disks in a raid1z set and waited for all the resilvering...the only problem is, my pool capacity is still exactly the same. Moving from 3x8Gb disks in raid1z giving ~16Gb space to 3x20Gb disks, and I still have ~16Gb usable space. I used the following commands to do the changes: zpool replace tank c1t1d0 c2t0d0 zpool replace tank c1t2d0 c2t1d0 zpool replace tank c1t3d0 c2t2d0 Where c1x are the old 8Gb disks and c2x are the new 20Gb disks. Is there something I missed? Thanks Matt _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
