I am facing an error while setting up cloud system, following issue
arises when management server machine requests hypervisor to launch
CP/SS VM's. After this request hypervisor tries to contact primary
storage to access storage but that primary storage server doesn't
responds, following are the logs from Xenserver hypervisor.

(hypervisor machine reboots itself after that due to HA enabled)
Primary storage server logs are below. (centos machines)
Feb 12 04:51:00 storage-server rpc.mountd[1751]: authenticated mount
request from 10.11.17.32:788 for /export/primary (/export)
Feb 12 04:51:00 storage-server rpc.mountd[1751]: authenticated unmount
request from 10.11.17.32:801 for /export/primary (/export)
Feb 12 04:51:00 storage-server rpc.mountd[1751]: authenticated mount
request from 10.11.17.32:830 for /export/primary (/export)
Issue seems to be strange because all necessary NFS ports are open in
sysconfig/nfs file, iptables service is also off and both machines can
ping each other successfully.
