Comment 5 SATHEESARAN 2021-03-17 09:31:55 UTC

This issue will be fixed with gluster-ansible which disables the option lookup-optimize in RHV 4.4.5 based RHHI-V deployments

Comment 7 Gobinda Das 2021-03-17 14:34:43 UTC

As per our discussion with QE, we agreed that now will go with gluster-ansible sid fix for RHHI-V-1.8.4.
Upstream patch: https://github.com/gluster/gluster-ansible-features/pull/47

Comment 8 SATHEESARAN 2021-03-24 13:11:35 UTC

The option to disable lookup-optimize on the gluster volume is achieved in 2 ways.
RHGS 3.5.4 has disabled this option through virt profile. Verified the same with glusterfs-6.0-55.el8rhgs
On the other hand, the ansible deployment module also disabled this option during deployment.

RHHI-V 1.8.4 will be using the update ansible deployment module ( gluster-ansible-features-1.0.5-11.el8rhgs ),
which disables this option during gluster deployment phase.

This option is also qualified. This bug will be verified once the required gluster-ansible-features package is available
with RHVH 4.4.5
