Defragmentation in Portworx reorganizes storage blocks to reduce fragmentation caused by frequent write and delete operations. Scheduling defragmentation during low workload periods ensures minimal impact on application performance while improving storage efficiency and I/O throughput. This optimization leads to faster read/write operations and prolongs the lifespan of storage devices by minimizing random I/O. Portworx provides administrators the ability to define defragmentation windows and recurrence policies within cluster configurations to automate this process. The official Portworx documentation explains that carefully timed defragmentation is critical to maintaining optimal cluster performance without disrupting business-critical workloads, making it an essential part of ongoing cluster maintenance and operational health【Pure Storage Portworx Performance 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】.

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】

Adding a new drive to an existing Portworx storage cluster involves bringing the physical device online for Portworx management. The correct command for this is pxctl service drive add -drive /dev/dm-1 -operation start. This command instructs Portworx to recognize and incorporate the new drive specified by the device path (e.g., /dev/dm-1) into its storage pool. After this operation, Portworx can use the drive for provisioning volumes or expanding capacity. The -operation start flag signals Portworx to initialize and prepare the drive for use. This method is part of Portworx’s dynamic storage management capabilities, allowing flexible scaling of storage resources without downtime. Official CLI documentation outlines this command as the supported approach to adding drives to running clusters safely and efficiently【Pure Storage Portworx CLI Guide†source】.
