Yes, vdevs allow you to expand your zpool. One zpool consists of groups of hard drives. Your zpool consists of one group of drives. That group contains 4 drives that are 2TB. You can easily add another group of drives to your zpool.
You can not change the number of discs of a group, but you can add several groups. Each group is called a vdev. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
