  • ONTAP 9.8
  • FlexCache volume

Answer

  • In FlexCache, files can only be evicted from the cache because of space constraints.
    • The scrubber begins when any of the constituents are more than 90% full.
  • If the constituent size is smaller than the file size being cached, ONTAP still attempts to cache the file.
  • This results in evictions from the cache because of size.
  • The data saved in cache can't be deleted manually.
