Applies to
ONTAP 9
Issue
- LUN in a thin provisioned volume taken offline due to volume running out of space although there is a large amount of aggregate free space.
- LUN shows 100% utilization in ONTAP, but client-side occupied space is lower and LUN is taken offline due to lack of space.
- LUN in a thin provisioned volume taken offline due to volume running out of space.
Example volume configuration:
- Fractional reserve disabled (
0%) - LUN space reservation is
off - Volume guarantee is
none - Volume autogrow is
off - Snapshot autodelete is
off
- Thin provisioned LUN in a thick provisioned volume went offline due to volume running out of space.
