I don't think you can do that within a single pool. But you can fake it like so: zpool create newpool lun1 lun2 lun3 lun4 lun5 lun6 lun7 lun8 zfs send oldpool | zfs recv newpool zpool destroy oldpool zpool rename newpool oldpool The commands are not exact, read the man pages to get the exact syntax for the send/recv part. However, doing so will make the pool extremely fragile. Any issues with any of the 8 LUNs, and the whole pool dies as there is no redundancy. -- Freddie Cash fjwc...@gmail.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
