I know oVirt don't support disperse, that's why i run gluster outside of oVirt. And doing that i get a bit more freedom with setting up gluster. So what would be an good setup to be able to use as much space as possible and some redundancy with the 4 hosts i have?

Even if you run gluster outside of oVirt, you are using the disperse volume as storage domain? For a supported config, you can create a distributed-replica+arbiter gluster volume. Since you have 12 disks, you can use a 5 x 3 (arbiter) setup, where a disk is partitioned to multiple arbiter bricks, something like this (c11,c12, a31, a32 are arbiter bricks) : a1 b1 c11 a2 b2 c12 b3 c13 d1 a31 c2 d2 a32 c3 d3

Hello

I would like some suggestions on what type of solution with Gluster i should use.

I have 4 hosts with 3 disks each, i want to user as much space as possible but also some redundancy, like raid5 or 6 The 4 hosts are running oVirt on CentOS 7 I have 2 clusters due to some licensing issues, so i cant use ovirts setup of gluster

I did not quite get this - are you saying you can have only 2 nodes in one cluster?

...

Today i have set it up as follows Type: Disperse Number of Bricks: 1 x (8 + 4) = 12

Disperse volumes are not supported with oVirt. It's either replica 3 or replica 2 + arbiter.

...

So i have 3 bricks per host (one brick per disk)

But this setup is not working very well, as soon as i get some traffic on the volume this start to fail on the ovirt nodes, loosing connection etc.

All hosts are connected via 10G interface

So any suggestions on how i would set this up as best is much appreciated.
