Hi, Storage Domains are DC entities and are not related to clusters. Every hosts in the DC should be able to access the Storage Domain. Once the SD is first created on one of the hosts, all the other host are trying to connect also. Can you mount manually from host2 ? It maybe a firewall/network issue.

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 RELATED,ESTABLISHED ACCEPT icmp -- anywhere anywhere ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:54321 ACCEPT tcp -- anywhere anywhere tcp dpt:54322 ACCEPT tcp -- anywhere anywhere tcp dpt:sunrpc ACCEPT udp -- anywhere anywhere udp dpt:sunrpc ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT udp -- anywhere anywhere udp dpt:snmp ACCEPT tcp -- anywhere anywhere tcp dpt:websm ACCEPT tcp -- anywhere anywhere tcp dpt:16514 ACCEPT tcp -- anywhere anywhere multiport dports rockwell-csp2 ACCEPT tcp -- anywhere anywhere multiport dports rfb:6923 ACCEPT tcp -- anywhere anywhere multiport dports 49152:49216 ACCEPT tcp -- anywhere anywhere tcp dpt:sunrpc ACCEPT tcp -- anywhere anywhere tcp dpt:nfs ACCEPT udp -- anywhere anywhere udp dpt:nfs ACCEPT udp -- anywhere anywhere udp dpt:sunrpc ACCEPT udp -- anywhere anywhere udp dpt:892 ACCEPT tcp -- anywhere anywhere tcp dpt:892 ACCEPT tcp -- anywhere anywhere tcp dpt:ospf-lite REJECT all -- anywhere anywhere 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)
