Description of problem: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Configuring_Red_Hat_Enterprise_Virtualization_with_Red_Hat_Gluster_Storage/chap-Recommended_Best_Practices_and_Troubleshooting.html recommends having replica 3. In fact, we must have replica 3 (I think this is enforced from 3.6).
Sas, can you confirm that replica 3 is a requirement rather than a recommendation when using RHGS to work with RHEV 3.6 and onward?

Laura, Still I see that replica 3 volume only as a recommendation. I tried setting up a distributed gluster volume for the backend of RHEV data domain with RHEV 3.6.5, and that works too. Only when optimising the volume for virt store it throws a suggestion to use replica 3 volume. As far as I can observe, the resstriction to use replica 3 volume is still not enforced Attaching the screenshot too
Created attachment 1156486 [details] optimizing the volume tab optimizing the volume for virt store suggests using replica 3 volume and doesn't enforces it
Yaniv, it looks like this is still a recommendation. Can you confirm so that we can close this NOTABUG, or provide more information?
It should be a requirement, period. The fact we are enforcing it in the product is a bug by itself. Y.
Whether it should be a requirement is another question altogether, I'm afraid. I've raised the question with product management; you should be on CC, Yaniv. :) For now, closing this NOTABUG.
Re-opening after confirmation from Sayan that replica 3 is required for support. Waiting on further information re. whether RHEV enforces this.
Yaniv, can you confirm that the changes in comment 9 solve the problem?
Sahina, anyone from the Gluster team can take a look at this?
Procedure 3.1 Please change note " Red Hat Gluster Storage recommends that you use Replicate or Distributed Replicate volume type for hosting virtual machine disk images. " - to indicate replica 3 requirements Procedure 4.1 Note about quorum - sas, can you recheck this section

The doc content looks good
