Previously, using the lookup-optimize option caused VM corruption on Red Hat Hyperconverged Infrastructure environments due to sharding and after shrinking or expanding the volume duirng a rebalance operation. With this update, the look-optimize option is disabled by default to avoid the corruption of Red Hat Hyperconverged environments.

Description SATHEESARAN 2021-03-17 10:05:21 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 1.7

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