Operate Portworx on VMware Tanzu

A Portworx cluster on Tanzu can contain a mixture of storage and storageless nodes. When scaling down a Tanzu cluster, one must be careful on not scale down the cluster size lower than the total number of storage nodes in the Portworx cluster.

You can find out the number of storage nodes by running “pxctl status” on any PX node. This will list all nodes in the cluster and mention which ones are storage nodes.

To control the number of storage nodes in the cluster, users can use the spec.cloudStorage.maxStorageNodesPerZone or spec.cloudStorage.maxStorageNodes configuration in the StorageCluster. Complete CRD reference of the StorageCluster is available here: StorageCluster
