Is it common for space reclaim to take days after deleting large TB volumes in ONTAP?

Last Updated:

Applies to



Yes, volume deletes are processed in the background and can take a while for the space to reclaim back to the aggregate.

Additional Information

  1. Verify if the volume is thick or thin provisioned
  • open the vol-status-v sections in autosupports
  • Find your volume and search for 'guarantee'
    • guarantee=volume [thick provisioned]
    • guarantee=none [thin provisioned]
  1. Review the metadata from the aggregate

::> storage aggregate show-space
 Aggregate : aggr0
      Feature                                          Used      Used%
      --------------------------------           ----------     ------   
      Volume Footprints                              2.89GB        90%
      Aggregate Metadata                             2.48MB         0%
      Snapshot Reserve                              163.8MB         5%
      Total Used                                     3.05GB        95%
      Total Physical Used                            1.51GB        47%

  • Wait at least 10 minutes and run the command again.
  • If the metadata is going down the space is reclaiming on the aggregate and the system is working as designed.
  1. Make sure there is nothing in recovery-queue

::> set diag
::*> volume recovery-queue show
