in qemu when accessing volumes on gluster storage domains you can try<br>
to apply this patch:<br>
<br>
<a href="http://gerrit.ovirt.org/33768" target="_blank">http://gerrit.ovirt.org/33768</a><br>
<br>
As far as I know Jason Brooks already tried it and he reported a<br>
positive feedback.<br>
<br>
What has been tested so far is:<br>
<br>
- qemu uses libgfapi to access the disks on gluster storage domains<br>
<br>
- hotplug of disks on gluster storage domains works as expected (libgfapi)<br>
<br>
- hotunplug works as expected (no failure when removing a disk that is<br>
using libgfapi)<br>
<br>
- live snpashots work as expected<br>
<br>
- disks of vms started before this patch are not affected (they won't<br>
use libgfapi since there's no way to do an hot swap)<br>
<br>
One major flow that is yet untested is live storage migration.<br>
<br>
Remember that you may need to do some special configuration on your<br>
gluster volumes (most notably the allow-insecure ports option) as<br>
described here:<br>

<br>
Please try and test the patch if you're interested and report your<br>
feedback.<br>
<br>
Thanks,<br>
