[ovirt-users] [Ovirt 4.0] Multiple cluster and multiple storage possible ?

Hi,

I am trying to setup ovirt as shown below.

DataCenter1 ---------Cluster1 -----host1 ---- NFS1-Data Domain
                      |
                      |-----Cluster2 ------host2-----NFS2-Data Domain


As you see in above case I am trying to attach both NFS partition to
Datacente1 and I got various behaviour:

1> Once one data domain attached to data center other is failing to
attached
(e.g. let say NFS1-Data Domain is attached to DataCenter1 then after that
NFS2-Data Domain failing to attach DataCenter1)

2> And sometime both data domain successfully got attached but after that
host2 is not coming up by saying "host1 cannot access to NFS2-Data Domain
and hence moving host1 to Non-Operational"
host1 firewall rules are :
--------------------------------------------------------------------------------------------------
# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere             state

dpt:ospf-lite
REJECT     all  --  anywhere             anywhere             reject-with
icmp-host-prohibited

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
REJECT     all  --  anywhere             anywhere             PHYSDEV match
! --physdev-is-bridged reject-with icmp-host-prohibited

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
--------------------------------------------------------------------------------------------------

Please help me to understand this issue.
1> Do ovirt support multiple-cluster to multiple-storage data domain ?
2> Are those firewall rules correct or wrong ?
3> Can host1 access storage domain created on another cluster say host2 m/c
? (NFS technology)


Thanks,
