Portworx alerts are generated for several resource types within the storage cluster environment, primarily including Nodes, Disks, Pods, Namespaces, and Volumes. These alerts provide real-time notifications of events such as node failures, disk health degradation, volume status changes, pod crashes, or namespace-level issues affecting storage consumption or performance. Monitoring these resource types helps administrators proactively manage cluster health, maintain high availability, and troubleshoot faults before they impact applications. The Portworx alerting framework aggregates data from these resources and integrates with external monitoring systems for centralized alert management. Official Portworx observability and alerting documentation list these resource categories as the core focus of Portworx alerting mechanisms, critical for operational awareness and automation【Pure Storage Portworx Observability Guide†source】.

To collect a comprehensive support bundle for Portworx Autopilot, the proper procedure is to create a dedicated directory, send a support signal to the running Autopilot process to trigger diagnostics collection, and then the generated support bundle files from that directory. This approach ensures all relevant Autopilot logs, configuration files, and runtime metrics are gathered in a structured way, enabling effective troubleshooting and root cause analysis. Simply restarting or deleting pods is insufficient, as it does not guarantee a full diagnostics capture. The Portworx troubleshooting and support documentation outlines this method as the standard for collecting detailed Autopilot support information, facilitating accelerated support response and issue resolution in production clusters【Pure Storage Portworx Support Guide†source】.

Upgrading Portworx clusters managed by the Kubernetes Operator requires a declarative update to the StorageCluster Custom Resource Definition (CRD). Specifically, the administrator must edit the StorageCluster resource and update the .spec.image field to point to the new version image, such as changing portworx/oci-monitor:3.0 to portworx/oci-monitor:3.1. This change instructs the Operator to roll out the new image across the cluster nodes, performing a seamless upgrade with minimal downtime. The pxctl CLI does not perform upgrades in Operator-managed environments; it is primarily for direct cluster management. The Operator ensures orderly upgrade sequencing, node by node, handling pod restarts and health checks. Automatic upgrades without manual intervention are not currently supported to prevent unintentional disruptions. Official Portworx upgrade documentation details this procedure, emphasizing the importance of version pinning and controlled rollout for production stability and rollback capabilities during upgrades【Pure Storage Portworx Upgrade Guide†source】.

To verify a Portworx upgrade on Kubernetes, administrators use the pxctl get storagenodes command. This Portworx CLI command lists all storage nodes with detailed information including version, status, and health. By inspecting the version column, administrators can confirm whether all nodes have been successfully upgraded to the desired Portworx release. This command specifically queries Portworx daemons for accurate cluster version details, unlike kubectl get nodes which shows Kubernetes node info but not Portworx versioning. Portworx upgrade best practices stress using pxctl commands for detailed verification after an upgrade to ensure consistent cluster software versions and successful upgrade completion【Pure Storage Portworx Upgrade Guide†source】.

Portworx integrates with three primary external secret stores to manage encryption keys securely: AWS Key Management Service (AWS KMS), Google Cloud Key Management Service (Google Cloud KMS), and Kubernetes Secrets. AWS KMS enables secure key storage and management for workloads running in AWS, leveraging native cloud security features. Google Cloud KMS provides similar key management for Google Cloud environments, allowing seamless integration with Google’s security infrastructure. Kubernetes Secrets provide an on-premises or hybrid cloud method to store encryption keys and sensitive configuration securely within Kubernetes clusters, suitable for private data centers or cloud-agnostic deployments. This multi-cloud and hybrid cloud compatibility enable Portworx to meet diverse customer requirements for key management and regulatory compliance. Portworx security documentation details the setup, configuration, and best practices for each supported secret store to ensure data encryption keys are managed securely and efficiently across environments【Pure Storage Portworx Security Guide†source】.

Dynamic Provisioning in Kubernetes with Portworx StorageClasses enables automatic, on-demand creation of storage volumes as requested by applications through Persistent Volume Claims (PVCs). This eliminates the need for administrators to manually create and manage volumes, significantly improving operational efficiency and accelerating application deployment. StorageClasses encapsulate parameters such as replication, encryption, and IO profiles, ensuring consistent volume configuration. Dynamic Provisioning also supports scaling and workload agility by provisioning storage transparently based on application needs. This feature is central to cloud-native storage management and is well documented in both Kubernetes and Portworx installation guides. It contrasts with manual volume creation, which is labor-intensive and error-prone, thus dynamic provisioning enhances automation and simplifies storage lifecycle management【Pure Storage Portworx Kubernetes Guide†source】.

Skinny Snapshots are a space-efficient snapshot technique used by Portworx for replicated volumes (Repl 2 or 3) when storage capacity is limited and no external Object Store is configured. Unlike full snapshots that duplicate data blocks, skinny snapshots capture only the differences (deltas) since the last snapshot, minimizing space consumption. This method allows administrators to take frequent snapshots without significantly impacting storage availability. Skinny Snapshots are particularly useful for on-premises environments or clusters without access to cloud object storage, balancing snapshot granularity with resource constraints. Official Portworx snapshot documentation explains how skinny snapshots work internally, improving backup and recovery capabilities under tight storage conditions without requiring cloud integration【Pure Storage Portworx Snapshot Guide†source】.

The command pxctl cluster status provides a concise summary of the Portworx cluster’s health and operational status. This includes node states, storage pool information, volume statuses, and quorum information. It is the primary CLI command for administrators to quickly assess cluster health and detect any issues affecting storage availability or performance. helm list --px is a Helm package management command unrelated to cluster status, and kubectl get pxstatus is not a valid Kubernetes or Portworx command. Portworx documentation recommends pxctl cluster status as an essential monitoring command during routine operations and troubleshooting to ensure the cluster is functioning properly and that all nodes are communicating and healthy【Pure Storage Portworx CLI Guide†source】
