Looking at the code, it looks like you need a Storage helper called GLUSTERFSStorageHelper in package org.ovirt.engine.core.bll.storage.

Which is introduced by Sharad's this patch: http://gerrit.ovirt.org/8834<= /a>
I guess you don't have this patch in your local repository.

In this patch, you will need to rename the file as it's case sensitive on linux- GlusterFsStorageHelper should be GLUSTERFSStorageHelper.

Hope this helps,
cheers

T= he NPE seems to be because the Storage helper is null for the storage type.

Hi All,
I am trying to compile ovirt engine after applying s= harad's glusterfs domain support patches @
http://gerrit.ovirt.org/#/q/project:ovirt-engine+branch:ma= ster+topic:glusterfs,n,z

After compiling, deploying the engine ( by following the steps in wiki.ovirt.org/Building_Ovirt_Engine )
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.

Then I select New SD->None in DC -> select my vdsm host->provide the args (remote path =3D volfileserver:volume, vfstype=3Dglusterfs, mount =3D> left blank) and click on OK
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.

I have captured the logs on the engien and vdsm side and attached here.

I am looking for some help on why the NPE is being seen on the engien side during adding a new SD ?

thanx,
deepak
