Hello,
As You will already have 5 copies (one per server), adding rendundancy on storage is wasty.
I would do a 2 node distributed + replication:
2 servers * 4 disk = 8TB replicated to 2 others servers with same setup.
The last server can be abitrer for split brain maybe, or you have to get another server to get 3 and 3.
Yes in this setup it's a raid 0, so if you loose a disk, the whole 2 replicated server are down.
But you will get much better performance and much more usable space, and still survive a single server crash.

Hi there,We are setting up 5 new servers with 4 disks of 1 TB each.We are planning of using Glusterfs Distributed Replicated so we have protection over our data.My question is, if I lose a disk, since we are using LVM mirror, are we still able to access the data normally until we replace the broken disk. And, in this scenario, out of the 20 disks, how many usable ones will I have?Thanks
