I'm learning more and more and I'm really beginning to like ZFS! Question: What happens if 1 drive out of say 4 fails in a pool? And what about hotswapping a (faulty) drive? Is this still possible with ZFS? Can I actually replace a Raid 5 setup with a ZFS settup and have the same data security if drives fail?' Cheers, Andy
