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.
That's incorrect. zfs pools can be expanded at any time. AFAIK zfs has always had this capability.
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.
I wasn't aware that Netapp could rebalance. Is that a true Netapp feature, or is it a matter of copying the data "manually"? zfs doesn't have a cleaner process that rebalances, so for zfs you would have to copy the data to rebalance the pool. I certainly wouldn't make my Netapp/zfs decision based on that (alone). -frank _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
