Recently I talked to a co-worker who manages NetApp storages. We discussed size changes for pools in zfs and aggregates in NetApp.
And some time before I had suggested to a my buddy zfs for his new home storage server, but he turned it down since there is no expansion available for a pool. And he really wants to be able to add a drive or couple to an existing pool. Yes, there are ways to expand storage to some extent without rebuilding it. Like replacing disk with larger ones. Not enough for a typical home user I would say. And this is might be an important for corporate too. Frankly speaking I doubt there are many administrators use it in DC environment. Nevertheless, NetApp appears to have such feature as I learned from my co-worker. It works with some restrictions (you have to zero disks before adding, and rebalance the aggregate after and still without perfect distribution) - but Ontap is able to do aggregates expansion nevertheless. So, my question is: what does prevent to introduce the same for zfs at present time? Is this because of the design of zfs, or there is simply no demand for it in community? My understanding is that at present time there are no plans to introduce it. --Regards, Roman Naumenko ro...@naumenko.com -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
