When gluster is upgraded, we update the volfiles in the post install part of package installations. In container world, there is no such procedure. We kill the old container and bring up a new container with new Gluster packages. IMO, glusterd --xlator-option *.upgrade=on -N command is a idempotent operation which can be run before starting glusterd service in a container. Am I right?
