How to expand an A-SIS enabled volume that is nearing the vol size limit

Last Updated:

Applies to

  • Data ONTAP 7
  • Data ONTAP 8


Deduplication has a maximum flexible volume size limit. If deduplication is to be used on a volume, that volume must be within the size limit. If an attempt is made to enable deduplication on a volume that is larger than the maximum volume size, it fails with an appropriate error message. If an upgrade occurs to a version of Data ONTAP that has larger maximum flexible volume size limits, then the larger size limits will be in effect once the upgrade is complete.

The maximum volume size limit varies based on the platform and Data ONTAP version. This is an important consideration if the flexible volumes are moved to a different platform with a smaller maximum flexible volume size.
