In your case it seems reasonable, but you should test the 2 stripe sizes (128K
vs 256K) before running in production. The good thing about replica volumes is
that you can remove a brick , recreate it from cli and then add it back.

Hello,
I am planning to use (6) 1 TB disks in a hardware RAID 6 array which will
yield 4 data disks per oVirt Gluster brick.
However.

One important step is to align the XFS to the stripe size * stripe width. Don't
miss it or you might have issues.

More questions on this -- since I have 5 servers . Could the following work ?
Each server has (1) 3TB RAID 6 partition that I want to use for contiguous
storage.
Mountpoint for RAID 6 partition (3TB) /brick
Server A: VOL1 - Brick 1 directory
Hello,
We have decided to get a 6th server for the install. I hope to set up a 2x3
Distributed replica 3 .
So we are not going to worry about the "5 server" situation.
Thank You All For Your Help !!

You can setup your bricks in such way , that each host has at least 1 brick.
For example:
Server A: VOL1 - Brick 1
Server B: VOL1 - Brick 2 + VOL 3 - Brick 3
Server C: VOL1 - Brick 3 + VOL 2 - Brick 2
Server D: VOL2 - brick 1
The most optimal is to find a small system/VM for being an arbiter and
Thanks Jayme !
I'll read up on it.
Thanks Again For Your Help !!

Jayme,
Thank for getting back with me !
If I wanted to be wasteful with storage, could I start with an initial
replica 2 + arbiter and then add 2 bricks to the volume ? Could the arbiter
solve split-brains for 4 bricks ?
Thank You For Your Help !

You can only do HCI in multiple's of 3. You could do a 3 server HCI setup
and add the other two servers as compute nodes or you could add a 6th
server and expand HCI across all 6
