<div>The only command I tried was <span style="background-color:rgba(255,255,255,0)">engine-config -s LibgfApiSupported=true but the result is what is shown in my output below, so it’s set to true for v4.2. Is it enough?</span></div>

<div> The procedure to enable gfapi is below.</div>
<div> </div>
<div>1) stop all the vms running</div>
<div>2) Enable gfapi via UI or using engine-config command</div>
<div>3) Restart ovirt-engine service</div>

<br>
I'm using the latest 4.2 beta release and want to try the gfapi access, but I'm currently failing to use it.<br>
<br>
My test setup has an external glusterfs cluster v3.12, not managed by oVirt.<br>
<br>
The compatibility flag is correctly showing gfapi should be enabled with 4.2:<br>
<br>
# engine-config -g LibgfApiSupported<br>
LibgfApiSupported: false version: 3.6<br>
LibgfApiSupported: false version: 4.0<br>
LibgfApiSupported: false version: 4.1<br>
LibgfApiSupported: true version: 4.2<br>
<br>
The data center and cluster have the 4.2 compatibility flags as well.<br>
<br>
However, when starting a VM with a disk on gluster I can still see the disk is mounted via fuse.<br>
<br>
Any clue of what I'm still missing?<br>
<br>
Thanks,<br>
<br>
<br>
Alessandro<br>
