This is request for comments for the new operating version (op-version) feature that is going to be introduced for glusterd. “operating-version” support in 'glusterd' is required to ensure that different versions of gluster binary bits interact with each other without problems.
More details regarding the feature can be found at http://www.gluster.org/community/documentation/index.php/Features/Opversion
Thanks,
Kaushal
