OneFS Cluster Quick Checks

OneFS brings simplicity, scalability, and ease of use to unstructured data management complexity. However, as with many things in life, an ounce of prevention is key to keeping a cluster happily humming along. As such, the following daily, monthly, and quarterly checks provide a quick and easy method for keeping an eye on a PowerScale environment and ensuring smooth cluster operation.

1 Daily Checks
Daily health checks are important to ensure a cluster is operating at optimal performance and capacity. These checks require minimal effort and develop familiarity: Ie. Becoming aware of alerts that point to an area of interest, or something requiring further investigation, before it becomes something larger.
Category Check Method Option(s) Description / Recommendation
Health Score CloudIQ, Alerts Target a Health Score of 100
Cluster Capacity WebUI, CLI, DataIQ, InsightIQ, CloudIQ, Alerts Maintain a storage utilization below 90%
Events and Alerts WebUI, CLI, Alerts Address all Hardware and Software Alerts as they occur

2 Monthly Checks
Monthly cluster health checks help ensure the environment is performing as expected, while also providing an opportunity to measure progress against service level objectives and review new OneFS feature enhancements.

SRS/Alerts/Events/Email WebUI, CLI, SRS Confirm that all alerting and notifications are operating as planned
Failed Drive Status WebUI, CLI Review drive status and ensure that all drives that have SmartFailed have been replaced

SnapshotIQ WebUI, CLI Snapshot utilization above 10% or any single snapshot possessing excessive size

[Ex. fsa snapshot]

SyncIQ WebUI, CLI Check the SyncIQ configuration to ensure RPO/RTO targets and required data is being replicated as needed
Monitoring Tools CloudIQ, DataIQ, InsightIQ Confirm that all monitoring tools are continuing to gather data from all storage devices
Healthcheck Framework CLI Ensure that the latest Healthcheck Framework checks are installed and Healthcheck Assessment is executed
