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 creat=
ed. 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.
...
From the second, if I change the value of Defaultver  /etc/nfsmount.conf fr=
om "Defaultvres=3D4" to "Defaulvers=3D3", the mount can not be done. When I=
 changed it back to "Defaultvers=3D4", it will work.
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,
Cong

Subject: Can not connect to Storage domain data

Hi

I successfully deployed the first ovirt host with hosted-engine -deploy. En=
gine 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 envi=
ronment.

The issue I have is in the engine administration menu, it says "can not con=
nect to storage domain data"
In the second host, I checked with nfs-check.py for both storage and data d=
omain. It shows the status is ok.
http://www.ovirt.org/Troubleshooting_NFS_Storage_Issues

During deployment of the second host, how the data domain is trying to be m=
ounted?

Thanks,
