[ovirt-users] Re: Scale out ovirt 4.3 (from 3 to 6 or 9 nodes) with hyperconverged setup and Gluster

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.
