Description of problem: I was going thro' an old mailing list thread http://www.gluster.org/pipermail/gluster-devel/2013-March/038857.html where the Opversion feature page was given as http://www.gluster.org/community/documentation/index.php/Features/Opversion . But that mediawiki link is now broken. It seems that the stuff in Mediawiki was moved over to ReadTheDocs but I could not find the feature page for Opversion either in https://github.com/gluster/glusterdocs or https://github.com/gluster/glusterfs-specs. Hence raising the bug.
We didn't move stuff over to Mediawiki. We just turned off mediawiki one fine day as far as I know. This is a conversation we need to have.
