Hi
For a production environment i would not build a 2 node gluster, i would bu=
ild at least 3 nodes to have it much easier with the quorum.
Taking into account that you can use commodity hardware i would also sugges=
t to split the services, but i would go for at least 3 gluster nodes =96 wh=
ich add up to at least 5 nodes for a HA system.
If you want 4 in any case, then my suggestion would be to go for 4 replicas=
, each node has anything that it needs to run and you can basically use NFS=
to localhost for the storage which would make the nodes always access the =
local storage for the VMS, availability wise it makes no difference.
Cheers
Soeren

Subject: Re: [ovirt-users] gluster config in 4 node cluster
Hi,
As for me, I would build one cluster with gluster service only based on two=
nodes (replica 2), and the other one with virt service only based on other=
two nodes. I think this variant is more scalable in future.
PS. I am a new in oVirt, so do not except that I am wrong.

Hello,
How to optimal configure 4 node cluster for any one node goes to maintena=
nce without stopping VM ??
a) replica 4 - but it takes a lot of space
b) disperse 3+1 ( raid 5 ) - but bad performance and not visible by oVirt 3=
.7.2
c) stripe2+replica2 =3D but VM paused
any other idea ?
regs.
Pa.
