The problem is they might publish these numbers, but we really have no way of controlling what number manufacturers will choose to use in the future.
If for some reason future 500GB drives all turn out to be slightly smaller than the current ones you're going to be stuck. Reserving 1-2% of space in exchange for greater flexibility in replacing drives sounds like a good idea to me. As others have said, RAID controllers have been doing this for long enough that even the very basic models do it now, and I don't understand why such simple features like this would be left out of ZFS. Fair enough, for high end enterprise kit where you want to squeeze every byte out of the system (and know you'll be buying Sun drives), you might not want this, but it would have been trivial to turn this off for kit like that. It's certainly a lot easier to expand a pool than shrink it! -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
