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】

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】.

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】.
