Capacity: Meta Device Capacity Percent Used (BUI)

This statistic shows the percentage of space used on a meta device, broken down by pool name. This statistic provides trending data, similar to the statistic Capacity: Capacity Percent Used (BUI).

Use this statistic to monitor meta device storage usage as a percentage, examine the trend of meta device usage, and to alert when capacity reaches a specific threshold.

This statistic is useful only when meta devices are configured for data deduplication.

When to Check Capacity Percent Used

This statistic can be used as a threshold alert for the percentage of used meta device capacity. A high percentage use indicates a need to add more meta devices to the configuration. Oracle ZFS Storage Appliance generates an alert when a meta device, used in any pool, reaches a threshold of 85 percent. If the threshold is exceeded and an alert is triggered, you can mitigate the situation before a meta device becomes too full and performance is impacted.
