Description SATHEESARAN 2016-01-05 06:15:53 EST
Description of problem:
-----------------------
There was already a bug 1260863 to add a recommendation to use replica 3 volume for virt store usecases. (i.e) RHEV Data Domain backed by replica 3 gluster volume.

The recommendation was available, but still there are few places in the guide which needs to modified to convey the same information to the readers/users


Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHGS 3.1.1 

Expected results:
-----------------
Remove the old information about RHEV Data Domain backed by replica 2 volume
from the guide.

The places which needs to be modified are :

1. Chapter 5 - "Recommended Best Practices and Troubleshooting"

Point 2 - "Red Hat Gluster Storage Volumes that serve as Red Hat Enterprise Virtualization Master Storage Domain contain SANLocks and have the Red Hat Gluster Storage volume profile set to virt. This enables the Client Side Quorum for 2-way Automatic File Replication and avoids the inconsistency problems for Multiple Writer situations. "

This should be - "Red Hat Gluster Storage Volumes that serve as Red Hat Enterprise Virtualization Master Storage Domain contain SANLocks and have the Red Hat Gluster Storage volume profile set to virt. This enables the Client Side Quorum and avoids the inconsistency problems for Multiple Writer situations."

Remove point 3
point 3 - "Disable the client side quorum for Red Hat Gluster Storage volumes that host Virtual Machines images for high-availability with 2-way replication."
