Installing Portworx using Operator with node specifics

This post shares various examples with which you can modify your Portworx Operator Cluster spec for node specific installation
Portworx Operator CRD Reference : StorageCluster

Cluster with Storage and Storageless nodes with a shared Data & Internal KVDB device

  • Make sure to label the nodes as given before applying the spec.
  • Nodes labeled as storage will use specific device /dev/sdb for data and KVDB both.

Cluster with Storage and Storageless nodes with dedicated Data and Internal KVDB devices

  • Make sure to label the nodes as given before applying the spec.
  • Nodes labeled as storage will use all available storage devices for storing data and /dev/sdc for KVDB seperately.

Cluster with Storage and StorageLess nodes with specific Internal KVDB nodes.

  • Suitable if you are planning to have more than 3 Storage Nodes with internal KVDB.
  • Nodes with kvdbnode will become Storage Node with dedicated disk on each node.
  • Nodes with storageless will not consume any disks.
  • If any of the remaining nodes do not have the dedicated device for KVDB, they will become storage nodes without dedicated KVDB devices.
