--_000_D19165E2D96Esoerenmalchowmconnet_ Content-Type: text/plain; charset="windows-1251" Content-Transfer-Encoding: quoted-printable 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.
