Didn't he give a use case? My use case is that I want to use ZFS for my archive disk, but before the disk gets too old I want to add another two disks when they are cheaper so I have a redundant 3 disk array. Another use case of mine is that I want to start a new storage server with 3 disks, but I anticipate running out of space by an unknown amount, so I want to be able to add a couple more disks when I need to. Seeing the demand for this is not rocket science. Hardware RAID5 adapters, NAS boxes, and Linux all support this feature. -- This messages posted from opensolaris.org
