Scaling GlusterFS clusters
This guide assumes that you have used the Maestro Add-in for GlusterFS. If you have configured the service manually then this will not apply
You can scale your GlusterFS clusters (up or down) using the Maestro dashboard:
- Open the Application Overview from your Dashboard
- Click on the Servers tab at the top of the main panel
- Find your GlusterFS server(s) and click the green + to scale up.
When you are scaling up, cloud66 will add servers to your cluster based on
replica_count(i.e if your
replica_count is 2, the number of servers could be 2,4,6…).
After Server deployment is finished, Maestro will create new bricks for current volumes and add them to GlusterFS cluster.
When you are scaling down, Maestro will remove the server (and all related servers which scaled up with this server) and remove their bricks for current volumes from GlusterFS Cluster

replica_count when you configure the GlusterFS Add-in. If you are using a manifest to add GlusterFS, you can add replica_count to your
