Answer

  • No, it is not required since ONTAP ugrade processes only involve root volume.
  • Even if deduplicated volumes and aggregates doesn't contain sufficient free space, it will not affect ONTAP update but the efficiency might not work normally.

Additional Information

What you'll need:

  • For a FlexVol volume, you must have verified that enough free space exists for deduplication metadata in volumes and aggregates.
  • The deduplication metadata requires a minimum amount of free space in the aggregate.
  • This amount is equal to 3% of the total amount of physical data for all deduplicated FlexVol volumes or data constituents within the aggregate.
  • Each FlexVol volume or data constituent should have 4% of the total amount of physical data's worth of free space, for a total of 7%.
