Doc Type: Bug Fix

Previously, lookup-optimize option could cause VM corruption on Red Hat Hyperconverged Infrastructure for Virtualization (RHHI-V)environment. With this update, lookup-optimize option is disabled by default post RHHI-V deployment hence there is no VM corruption.

Description SATHEESARAN 2021-03-17 09:41:59 UTC 
Description of problem:
------------------------
RCA for the bug https://bugzilla.redhat.com/show_bug.cgi?id=1938110 turned out to be because of the option - 'lookup-optimize' enabled on the volume. 

There is a separate bug (https://bugzilla.redhat.com/show_bug.cgi?id=1939372) that disables the option in virt profile

But RHVH 4.4.5 will be available to customer well before RHGS 3.5.4, and considering the severity of the issue, it was planned to disable this option in the gluster-ansible task that optimized the volume for virt-store use case


Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHHI 1.8

Expected results:
------------------
Disable lookup-optimize option as part of gluster-ansible task

Comment 4 SATHEESARAN 2021-04-05 17:44:31 UTC 
verified with gluster-ansible-features-1.0.5-11.el8rhgs

The volume option 'cluster.lookup-optimize' is turned off post gluster deployment

[root@ ~]# rpm -qa | grep gluster-ansible-features
gluster-ansible-features-1.0.5-11.el8rhgs.noarch

[root@ ~]# gluster volume get engine lookup-optimize
Option                                  Value                                   
------                                  -----                                   
cluster.lookup-optimize                 off
