This is a good point. If the storage is in use for a number of years, it may be best to replace the existing drives with new larger drives so the existing layout remains optimal. Also, consider adding or replacing drives when 60-80% of the space is used so that new data can still be written reasonably optimally. Raw disk space is cheap. Unfortunately, I am not aware of a zfs subcommand which displays the amount of storage space consumed from each drive. Perhaps one should be added.
