<pre>Hi,<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I started to learn the oVirt by following the oVirt Quick Start Guide.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I used one server as the ovirt.engine, and another server as the ovirt.host. Both servers run Fedora 18.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>After executing the command "engine-setup" in the ovirt.engine, I can get into the admin portal to start the configuration of host, storage, etc. Here was what I am doing:<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre><o:p> </o:p></pre>
<pre>1. In the Default data center, I clicked the Guide Me icon. The first thing is to configure the host. After waiting for 4-5 minutes, I saw the host ovirt.host is displayed under the Host tab with the Up status.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>2. On the ovirt.engine server, I did the following before creating the storage:<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>mkdir -p /mnt/data<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>chown -R 36:36 /mnt/data<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Add the following line to /etc/sysconfig/nfs:<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre> NFS4_SUPPORT="no"<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>Add the following line to /etc/exports:<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre> /nmt/data *(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>systemctl restart nfs-server.service<o:p></o:p></pre>
</blockquote>
<p class="MsoNormal"><br>
<br>
Well, exports has a typo error: /nmt/data instead of /mnt/data<br>
If that it's not enough, If you're using selinux ensure that /mnt/data has the correct context:<br>
<br>
/etc/selinux/targeted/modules/active/file_contexts.local:<br>
/mnt/data(/.*)? system_u:object_r:public_content_rw_t:s0<br>
<br>
<br>
<br>
<br>
<br>
<br>
<o:p></o:p></p>
<pre><o:p> </o:p></pre>
<pre><o:p> </o:p></pre>
<pre>3. Back to the Default data center, clicked the Guide Me icon to start the configuration of new storage.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>4. On the New Storage dialog, set Name field to be NFS-Share, and set the Export Path field to be ovirt.engine:/mnt/data. Then click OK<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>After couple of minutes, I saw the error window popped up: Error: Cannot add Storage. Internal error, Storage Connection doesn't exist.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre><o:p> </o:p></pre>
<pre><o:p> </o:p></pre>
<pre>From the /var/log/ ovirt-engine/engine.log, I can see:<o:p></o:p></pre>

<pre>Thanks,<o:p></o:p></pre>
<pre>Hongyi<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>P.S. If I create the NFS domain in the ovirt.host side (i.e., Export Path is ovirt.host:/mnt/data), then everything is okay. Not sure why failed on the ovirt.engine side.<o:p></o:p></pre>
