Ah, the bug I'm referring to may only apply to replica 3 gluster. You appear to be using an arbiter. It sounds like you may need to file a bug for this one On Mon, Feb 3, 2020 at 12:05 PM Christoph Köhler < koehler@luis.uni-hannover.de> wrote:
Hello Jayme,
the gluster-config is this:

I really do not know what to do new...

Chris, what is the storage configuration? I was under the impression that there was a bug preventing snapshots from working when using libgfapi on gluster replica configurations. This is one of the main reasons why I have been unable to implement libgfapi.

Hi,
since we have updated to 4.3.7 and another cluster to 4.3.8 snapshots are not longer possible. In previous version all went well...
° libGfApi enabled ° gluster 6.7.1 on gluster-server and client ° libvirt-4.5.0-23.el7_7.3

It seems that the origin is libvirt or qemu.
