[ovirt-users] adding 3 machines as gluster nodes to ovirt 4.0.4

Hi,

I have ovirt 4.0.4 running on a centos 7.2 machine.

I have 3 identical centos 7.2 machines I want to add as a gluster storage 3
way mirror array.  The admin guide doesnt seem to show how to do this?  I
have setup ssh keys for root access.  I have setup a 1TB LUN on each ready
for "glusterising".  I have tried to build and setup gluster before ahnd
and import the ready made setup but this locked up in "activating" and
after 36hours never completed (I assume they should move to "up"?)

Is there any documentation out there on how?   I want these as pure gluster
storage only nodes no VMs to go on them.  The VMs will go on 2 or 3 new
machines I will add later as a next stage.

I have tried to add them as hosts (not sure if this is the right method I
suspect not), but I get install failures in the engine.log

sample,

=========

ssh keys dont work either (so I had to set a password) even though root can
ssh via said keys so that is working OK.  Either a mistake by me, or a bug.

iptables is off,

=====

[root at glusterp1 ~]# iptables -L -n
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
[root at glusterp1 ~]#
=====

ideas please?


regards
Steven
