I have 2 hosts per cluster, and i have 2 clusters, 4 hosts (its an Huawei x6000)
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?

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.
Regards
Magnus Isaksson
