Trying to get gluster plugin to work in small 3 node RPI swarm

I’m trying to get the gluster plugin working but when I try to install it, it completes but I get this:

“Error response from daemon: dial unix /run/docker/plugins//gluster.sock: connect: no such file or directory”

I’m a total noob here working with docker swarm but I’m hoping someone can tell me what I’m doing wrong here.

As an FYI I installed glusterFS on all nodes and have three bricks running in the gluster cluster as replica’s but I found it made things act very strange with my nginx service which is currently serving up a web page that is generated from my weewx container (weather station software). It updates about every 2-3 seconds, so I’m not sure if this is the problem with the speed of replication or if I should even be using this at all?

Also, I can’t seem to find a good explanation of what happens to services and containers when a node fails in the swarm. Does the swarm recreate containers or service related containers as long as there are at least 2 nodes with one manager?
