oVirt 4.3.5 glusterfs 6.3 performance tunning
Hello, I have a hyperconverged setup using ovirt 4.3.5 and the "optimize for ovirt store" seems to fail on gluster volumes. I am seeing poor performance and trying to see how should I tune gluster to give better performance. Can you provide any suggestions on the following volume settings(parameters)? option Value ------ ----- cluster.lookup-unhashed on cluster.lookup-optimize on cluster.min-free-disk 10%

+Krutika Dhananjay <kdhananj@redhat.com> +Sachidananda URS <surs@redhat.com> Adrian, can you provide more details on the performance issue you're seeing? We do have some scripts to collect data to analyse. Perhaps you can run this and provide us the details in a bug. The ansible scripts to do this is still under review - https://github.com/gluster/gluster-ansible-maintenance/pull/4 But would be great if you can provide us some feedback on this as well.
