Found the following and answered part of my own questions, however I
think this sets a new set of Replica 3 Bricks, so if I have 2 hosts
fail from the first 3 hosts then I loose my hyperconverged?

When you add the new set of bricks, and rebalance, gluster will still respect your current replica value of 3. So every file that gets added, will get two copies placed on other bricks as well. You don't know which bricks will get a copy of said file. So the redundancy is exactly the same. You can lose 2 hosts out of all hosts in the cluster.

If that is not enough for you, you can increase the replica value at the cost of storage space.
