Spillover

When you activate a SmartPools license, you can designate a node pool or tier to receive spillover data when the hardware specified by a file pool policy is full or otherwise not writable.

If you do not want data to spill over to a different location because the specified node pool or tier is full or not writable, you can disable this feature.

Virtual hot spare reservations affect spillover. If the setting Deny data writes to reserved disk space is enabled, while Ignore reserved space when calculating available free space is disabled, spillover occurs before the file system reports 100% utilization.
