Looking at the code, it looks like you need a Storage helper called
GLUSTERFSStorageHelper in package org.ovirt.engine.core.bll.storage.
The NPE seems to be because the Storage helper is null for the
storage type.<br>Corret, this is based on reflection - if you have an enum literal of X then you must have an XStorageHelper, even if it has no meaningful functionality of its own (as in the case of POSIXFSStorageHelper). I assume such class can extend BaseFsStorageHelper<br>I<br><br>

<br>
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->None in DC -> select my vdsm
host->provide the args (remote path = volfileserver:volume,
vfstype=glusterfs, mount => 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>
deepak
