Most probably RH specialists can tune Gluster so well that the libgfapi is uselesss ... who knows. Actually, oVirt and support are 2 completely different topics. Yes, it has it drawbacks, butif it brings significant performance gain.

Unfortunately, the performance improvements that users have reported on this mailing list haven't been seen or replicated by Red Hat, so recently most of these bugzilla tickets have been closed as WONTFIX https://bugzilla.redhat.com/show_bug.cgi?id=1633642 https://bugzilla.redhat.com/show_bug.cgi?id=1465810 https://bugzilla.redhat.com/show_bug.cgi?id=1552344 This is a shame as I think the performance improvements from libgfapi as reported in user benchmarks were impressive, and the underlying qemu/libvirt bugs are now fixed or were close to be.

The qemu process should not use the '/rhev' mountpoints. Also, share your current setup:- disks- hw controller- did you storage align your block devices (hw raid only)- tuned-profile- sysctl settings that are changed- gluster volume options that are changed Best Regards,Strahil Nikolov_______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/FYVQBT4ZYTSFD6CQHX7L42HWUDI3ZDOF/ Ce message et toutes les pièces jointes (ci-après le “message”) sont établis à l’intention exclusive de ses destinataires et sont confidentiels.
