- ONTAP 9
This is expected behavior when the following environmental conditions are met:
- A space-reserved LUN in a volume with a space guarantee of VOLUME
- The fractional reserve on the volume is set to 0
- The volume has storage efficiency features (deduplication) enabled
- The LUN has space reservation honored = false
Space Reservation and
Space Reservation Honored please run the following command:
cluster1::> lun show -vserver vs1 -path /vol/vol1/lun1 -instance Vserver Name: vs1 LUN Path: /vol/vol1/lun1 Volume Name: vol1 Qtree Name: "" LUN Name: lun1 LUN Size: 10MB OS Type: linux Space Reservation: enabled Serial Number: xxxxxxxx Serial Number (Hex): xxxxxxxx Comment: new comment Space Reservations Honored: false ...
For more information regarding NetApp's best practice for LUN configuration please review, What is the proper configuration for a volume containing a LUN?
There is a current request for enhancement with our Engineering team to prevent this issue in future ONTAP releases.
