Recently , it was discussed in the mailing lists and dev mentioned that distributed
replicated volumes are not officially supported, but some users use them.
Even if not supported, it still should work without issues.If you think not to go this
way, you can create a new 3 node cluster which will be fully suppported.
Otherwise, if you go towards replicated distributed volumes , you just need to provide
another set of 3 bricks and once added you can rebalance in order to distribute the files
accross the sets.
Here is an old thread that describes it for replica 2 volume types:
https://lists.gluster.org/pipermail/gluster-users/2011-February/006599.html
I guess I have confused you with my last e-mail, but that was not intentionable.

Hi Strahil,
I had a 3 node Hyperconverged setup and added 3 new nodes to the cluster for a total of 6
servers. I am now taking advantage of more compute power, however the gluster storage part
is what gets me.
Current Hyperconverged setup:
- host1.mydomain.com
Bricks:
engine
data1
vmstore1
- host2.mydomain.com
Bricks:
engine
data1
vmstore1
- host3.mydomain.com
Bricks:
engine
data1
vmstore1
- host4.mydomain.com
Bricks:
- host5.mydomain.com
Bricks:
- host6.mydomain.com
Bricks:
As you can see from the above, the original first 3 servers are the only ones that
contain the gluster storage bricks, so storage redundancy is not set across all 6 nodes. I
think it is a lack of understanding from my end on how ovirt and gluster integrate with
one another so have a few questions:
How would I go about achieving storage redundancy across all nodes?
Do I need to configure gluster volumes manually through the OS CLI?
If I configure the fail storage scenario manually will oVirt know about it?
Again I know that the bricks must be added in sets of 3 and per the first 3 nodes my
gluster setup looks like this (all done by hyperconverged seup in ovirt):
engine volume: host1:brick1, host2:brick1, host3:brick1
data1 volume: host1:brick2, host2:brick2, host3:brick2
vmstore1 volume: host1:brick3, host2:brick3, host3:brick3
So after adding the 3 new servers I dont know if I need to do something similar to the
example in
https://medium.com/@tumballi/scale-your-gluster-cluster-1-node-at-a-time-..., if
I do a similar change will oVirt know about it? will it be able to handle it as
hyperconverged?
As I mentioned before I normally see 3 node hyperconverged setup examples with gluster
but have not found one for 6, 9 or 12 node cluster.
Thanks again.
