    In this patch, you will need to rename the file as it's case

          &nbsp;&nbsp; I am trying to compile ovirt engine after applying sharad's
          glusterfs domain support patches @ <br>
          <a class="moz-txt-link-freetext" href="http://gerrit.ovirt.org/#/q/project:ovirt-engine+branch:master+topic:glusterfs,n,z" target="_blank">http://gerrit.ovirt.org/#/q/project:ovirt-engine+branch:master+topic:glusterfs,n,z</a>
          <br>
          <br>
          After compiling, deploying the engine ( by following the steps
          in wiki.ovirt.org/Building_Ovirt_Engine ) <br>
          I connect to the weadmin GUI, add a VDSM host ( this is my own
          vdsm host with VDSM glsuter domain support ) and the host is
          "Up" state. <br>
          <br>
          Then I select New SD-&gt;None in DC -&gt; select my vdsm
          host-&gt;provide the args (remote path = volfileserver:volume,
          vfstype=glusterfs, mount =&gt; left blank) and click on OK <br>
          <br>
          I see NPE in the engine side during addStorageServer cmd (
          IIUC ) and then engine tries to send disconnectStorageServer,
          which reaches my VDSM host and it throws a excp, since the
          domain is not mounted at all. <br>
          <br>
          I have captured the logs on the engien and vdsm side and
          attached here. <br>
          <br>
          I am looking for some help on why the NPE is being seen on the
          engien side during adding a new SD ? <br>
          <br>
          thanx, <br>
