+++ This bug was initially created as a clone of Bug #1375431 +++

Description of problem:
-----------------------
Sharding seems to be most vital for the virt store usecase and this needs to be
turned when the volume is optimized for virt-store

The following options needs to be added to the virt profile -
/var/lib/glusterd/groups/virt

features.shard=on
cluster.data-self-heal-algorithm=full

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

How reproducible:
-----------------
Not applicable as this is a RFE

Steps to Reproduce:
-------------------
Not applicable as this is a RFE

Actual results:
---------------
sharding is not enabled by default by optimizing the volume for virt store

Expected results:
-----------------
Sharding should be enabled by default on optimizing the gluster volume for virt
store usecase

--- Additional comment from SATHEESARAN on 2016-09-14 09:08:42 EDT ---

strict-o-direct also needs to be turned on and remote-dio to be turned off

In total there are 4 options :

features.shard=on
cluster.data-self-heal-algorithm=full
performance.strict-o-direct=on
network.remote-dio=disable
