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 :

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,
