I found the workaround for this.

For some reason my Storage domain of data can not be mounted. I just mount it 
manually, like

mount -t nfs nfs2-3:/data /rhev/data-center/mnt/nfs2-3:_data

Actually, the folder of "/rhev/data-center/mnt/nfs2-3:_data" has been created. 
I think this may be some bug as for in my environment, I will reproduce it 
always if I try to deploy the host from second time.

Thanks,
Cong

I think the problems for my issue are related with the NFS version.

Also from /proc/mounts, it shows the nfs version is nfs4. But for my first 
host, it is nfs3.

Do somebody have the similar issue about thi?

Thank in advance,

Subject: Can not connect to Storage domain data

Hi

I successfully deployed the first ovirt host with hosted-engine -deploy. Engine 
VM works well.
While, when I try to create the second host with the same way as the guide of
http://community.redhat.com/blog/2014/11/up-and-running-with-ovirt-3-5-part-two/

I am not using GlusterFS, and just use one external storage(nfs) in my 
environment.

The issue I have is in the engine administration menu, it says "can not connect 
to storage domain data"
In the second host, I checked with nfs-check.py for both storage and data 
domain. It shows the status is ok.

During deployment of the second host, how the data domain is trying to be 
mounted?

Thanks,
