Issue

  • After upgrading to ONTAP 9.17.1P3 in cloud environments (for example AWS FSx), background deduplication does not run and storage efficiency remains in a “Pending” state.
    Example:

::> vol efficiency show
Vserver    Volume           State     Status      Progress             Policy
---------- ---------------- --------- ----------- -------------------- ----------
node-01    vol0             Enabled   Pending     Pending for 13:32:15 -
node-02    vol0             Enabled   Pending     Pending for 13:33:12 *-*
  • Customers may see unexpected snapshot size growth and reduced storage savings.
