+# gluster/consolidated
+
+Three things to know about this role:
+
+- It consolidates the gluster/server and gluster/client roles.
+- It gets gluster working on F25 and F26.
+- It requires a ton of open ports on the hosts for `gluster peer probe` to work.
+  See `inventory/group_vars/odcs-backend` for an example.
+
+Our older gluster/server and gluster/client roles only seemed to work for el7.
+The advice from `#gluster` was to use the `gluster_volume` ansible module
+instead of configuring the `.vol` file directly ourselves.  That is what this
+role does.
