Currently I am running 5x3TB in Z1 and want to add 5 more drives to get to 10x3TB Z2. I am using about 7.5GB. If I buy an 8TB drive to move everything I can fit over to, how do I go about wiping the pool and upgrading to a new single pool without making a mess of how jails like Plex see things? Or would this be time to do a clean install of freenas and redo all of the jails and settings. Any thoughts on the best way to do this?
