Scaling GlusterFS clusters

Note

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:

  1. Open the application overview page from your Dashboard
  2. Click on the Servers tab at the top of the main panel
  3. 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

Configure GlusterFS replica_count

You can specify 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 manifest.yml.

Note

You cannot change replica_count after GlusterFS has been added to your application.
