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】.

Portworx provides a declarative method to schedule automatic backups by configuring schedule policies within its Backup and DR framework. These policies specify when and how frequently backups should occur, retention rules, and target storage locations. By applying schedule policies, administrators enable Portworx to perform backups automatically without manual intervention or external scripting. Using cron jobs to run pxctl snapshot create is possible but less integrated, error-prone, and not recommended for scalable environments. The command px backup volume is not a valid Portworx CLI command. The Portworx backup documentation encourages using native schedule policies for reliable, maintainable, and policy-driven backup automation, supporting compliance and disaster recovery strategies【Pure Storage Portworx Backup Guide†source】.
