If Portworx logs indicate that a node is not in quorum, the administrator’s first step is to verify the status of each storage node in the cluster using the command pxctl status. This command provides detailed information about node connectivity, quorum status, and cluster health. The quorum is critical for distributed consensus and cluster consistency. Checking each node’s status helps identify network partitions, node failures, or communication issues causing quorum loss. Simply running pxctl service status provides service-level info but not the comprehensive node quorum details needed. The Portworx troubleshooting documentation stresses using pxctl status as the primary diagnostic tool when encountering quorum-related alerts to ensure cluster stability and resolve issues promptly【Pure Storage Portworx Troubleshooting Guide†source】.

The command pxctl list autopilotrules is used to list all Autopilot rule objects across namespaces within a Portworx cluster. Autopilot rules define automated policies for storage operations like scaling and volume migration. This CLI command queries the Portworx control plane to retrieve and display all configured Autopilot rules, regardless of the Kubernetes namespace they reside in. Using kubectl commands alone is insufficient because Autopilot rules are managed internally by Portworx and may not correspond directly to Kubernetes resources. Official Portworx CLI documentation confirms pxctl list autopilotrules as the primary command for comprehensive Autopilot rule enumeration, enabling administrators to audit and manage storage automation policies efficiently【Pure Storage Portworx Autopilot Guide†source】.

On-demand snapshots in Portworx allow administrators and applications to create point-in-time copies of volumes instantly without requiring downtime or interrupting running workloads. This capability is critical in Kubernetes environments where high availability and continuous operation are mandatory. Snapshots capture the exact state of data at a moment, enabling rapid recovery from accidental deletion, corruption, or ransomware attacks. Since these snapshots are created live, applications continue to run seamlessly, ensuring minimal impact on user experience. Portworx’s snapshot technology uses efficient -on-write mechanisms, which also minimize storage overhead. Official Portworx documentation emphasizes that on-demand snapshots enhance data protection strategies by enabling quick backups and restores without requiring maintenance windows or complex scheduling【Pure Storage Portworx Snapshot Guide†source】.
