Is it required to verify that deduplicated volumes and aggregates contain sufficient free space for ONTAP upgrade

Last Updated:

Applies to



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%.
