This GlusterFS volume will be used to persist data for services we run on the Docker Swarm that was previously set up on the cluster. The GlusterFS software needs to be installed on all of the nodes in the cluster. Here is here pssh makes it easy to set up all nodes at the same time. Now set up the GlusterFS volume from the master node and set the the master node’s firewall to enable all traffic from within the cluster’s LAN: With the last command, you should see the list of nodes all connected. node1 will be listed as localhost since you are currently on it. The next step is to create a GlusterFS volume. First a folder on the /mnt/brick partition is created on every Read More …
