<div class="">Hi,</div>
<div class="">where should I enable gfapi via the UI?</div>
<div class="">The only command I tried was <span style="background-color:
rgba(255, 255, 255, 0);" class="">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 class=""><span style="background-color: rgba(255, 255, 255, 0);" class="">I’ll
try restarting the engine. Is it really needed to stop all
the VMs and restart them all? Of course this is a test setup
and I can do it, but for production clusters in the future
it may be a problem.</span></div>

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