Hey Jayme,
thanks for replying; sorry for the delay. If I am understanding this right, there is no real official way to enable libgfapi. If you somehow manage to get it running then you will lose HA capabilities, which is something we like on our production servers.
The most recent post I could find on the matter (https://www.mail-archive.com/users@ovirt.org/msg59664.html) read like its worth a try for hobyyists, but for production servers I do am a little bit scared.
Do you maybe have any document or other source that does work with 4.3.x versions and inspires confidence? :-)

I strongly believe that FUSE mount is the real reason for poor performance in HCI and these minor gluster and other tweaks won't satisfy most seeking i/o performance. Enabling libgfapi is probably
best option. Redhat has recently closed bug reports related to

citing won't fix and one comment suggests that libgfapi was not showing good enough performance to bother with which appears to contradict what many oVirt users are seeing. It's confusing to me why libgfapi as a default option is not being given any priority.

"We do not plan to enable libgfapi for oVirt/RHV. We did not find enough performance improvement justification for it"
Hey All, Direct libvirt access via libgfapi causes loss of some features , but this is not the only option. You can always use NFS Ganesha, which uses libgfapi to reach the gluster servers, while providing access via NFS. Best Regards, Strahil Nikolov
