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】.

When security is enabled in Portworx, all commands, including those issued via the pxctl CLI, require authentication to access the cluster. If pxctl returns an “access denied” error, it means the CLI does not have valid credentials. To regain access, administrators must provide authentication details using the --user and --password flags or configure a context with an authentication token. The username and password are stored securely within the Kubernetes secret px-admin-token. Using these credentials ensures pxctl commands are authorized to perform management operations. Without authentication, Portworx enforces strict access controls to protect sensitive storage operations and data. While creating new contexts via pxctl context create is a valid method, initially supplying credentials is mandatory. Failure to authenticate prevents any management activity, reinforcing Portworx’s security posture. Official security guides outline these steps as fundamental to transitioning from unsecured to secured cluster operation and managing authenticated access effectively【Pure Storage Portworx Security Guide†source】.

If a drive fails and the associated storage pool contains critical metadata, the safest and recommended action is to decommission the entire node. Metadata loss can compromise the integrity of volume allocations and cluster state. Decommissioning the node allows Portworx to safely remove the node from the cluster, replicate data, and redistribute workloads, preventing data loss or corruption. Deleting the pool or reformatting the disk without proper precautions risks losing metadata and causing cluster inconsistencies. Portworx’s operational guidelines emphasize that nodes with failed drives holding metadata require careful decommissioning procedures to maintain cluster health and data durability, ensuring data is rebalanced and availability is preserved【Pure Storage Portworx Operations Guide†source】.
