Apigee hybrid recommended disk size for each node

[shalipriya]

Hi,

I would like to know the recommended disk size for each node in apigee hybrid(both runtime and data node ). Currently we have 20Gib for each node and we have issues with PV not creating.

Storage requirements can be found here https://cloud.google.com/apigee/docs/hybrid/v1.8/cassandra-production.

Please look at the storage class and check the storage class used in your overrides. if none, it has to be default. Next check the storage class provisioner. Based on that you can determine why the PV can't be provisioned. For cloud deployments like gke, the default storage class uses gce-pd which does dynamic volume provisioning in GCP so it's not an issue. If you are using file storage for your storage class, the disk size would matter. However its always good practice to use storage container provider like portworx or vm-storage if your are building on premise hybrid cluster.
