:-) What is the downtime for doing a send/receive? What is the downtime for zpool export, reconfigure LUN, zpool import? And you still need to shrink the pool. Move a 100Gb application from server A to server B using send/receive and you will have 100Gb stuck on server A that you can't use on server B where you relay need it. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
