Testing oVirt with Gluster 6
Hi, according to https://bugzilla.redhat.com/show_bug.cgi?id=1673058 the network throughput usage increases by a x5 upgrading from Gluster 3.12 to Gluster 5.y. This seems definitively problematic on our hyper-converged environments: I read more than one report where, over 1 Gbps network, sanlock could not be refreshed quickly enough and so killed the engine VM if not rebooted the host due to the watchdog. This is probably due to the fact that, according to that bug, the network got completely saturated. Faster networks seems still fine. https://bugzilla.redhat.com/show_bug.cgi?id=1673058 is probably going to be solved for Gluster 5.6. On the other side we have https://bugzilla.redhat.com/1693998 <https://bugzilla.redhat.com/show_bug.cgi?id=1693998> about rebasing over Gluster 6 which seems not affected by that issue. Do you have concrete plans about testing oVirt with Gluster 6? thanks, Simone
Hi Simone, Kaustav has upgraded from gluster-3.12 to gluster-6 and done some tests like VM creation and some pg bench testing. https://github.com/ezio-auditore/gluster-pg-bench-test-results But yeah as you said will have to plan for end to end testing with fresh installation also.

based on bug above, any plan to switch to Gluster-6 with oVirt 4.3 ? Simon

We are tentatively targeting rebase on Gluster 6 for 4.3.5: https://bugzilla.redhat.com/show_bug.cgi?id=1693998 Plan can change while we test it.

Gobinda, Sahina, Kaustav, any update on this testing? Are we ok to go with pushing the switch to Gluster 6 to master? One month passed and it's time to go on with this.

Hi, We have tested gluster 6 by running pg bench on a vm. Things are working fine. Here are the results https://github.com/ezio-auditore/gluster-pg-bench-test-results There is a small blog regarding this which is yet to be published.

Thanks, I'll push patches for switching to Gluster 6 on master and if no regressions will be found I'll push to 4.3 too.
