Applies to

  • MetroCluster
  • Switchover 
  • Aggregate size difference

Answer

  • ONTAP reserves 50% of the free space to expand snap-reserve capacity in order to allow faster resync when an aggregate goes to mirror-degraded state
  • Applies if snapshot-auto-delete is turned on, so that the reserved space can be reclaimed if needed
