Hello,
thanks for the hint, but wasn't it already there ? Many documents and screenshots show the radio-button to enable gluster on the cluster tab of the Engine Webinterfaces.
Gluster is fully supported - but it's using the FUSE mount right now. The idea is to move to the native libgfapi (built-in QEMU support for native Gluster protocol). See [1] for details. Y. [1] http://www.gluster.org/community/documentation/index.php/Libgfapi_with_qemu_...
Bye

Hello,
I set up 8 Hosts and self-hosted-engine running HA on 3 of them from gluster replica 3 Volume. HA is working, I can set one host of the 3 configured for hosted-engine to maintenance and engine migrates to other host. I did the hosted-engine --deploy with type gluster and my gluster hosted storage is accessed as glusterfs.mydomain.de:/engine
I set up another gluster volume (distributed replicated 4x2=8) as Data storage for my virtual machines which is accessible as glusterfs.mydomain.de:/gv0. ISO and Export Volume are defined from NFS Server.
When I set up a VM on the gluster storage I expected it to run with native gluster support. However if I dumpxml the libvirt machine definition I've something like that in it's config:
[...]

How do I get my most wanted feature native gluster support running ?
