vol0 (node root volume)
High IOPS

Answer

Internal ONTAP processes cause high IOPS on vol0
It is considered normal behavior

Additional Information

It is usually safe to ignore in most circumstances as this should have no performance impact to user workloads
Engineering has stated that this is normal, expected, and if observed no fix is needed in most circumstances
806862 High IOPS Observed on Root Volume/Aggregate
A couple other causes are listed in these two bugs:
- 726693 High input output operations per second (iops/s) of type other_iops seen on volume vol0
- 830749 High input output operations per second (iops/s) of type other_iops seen on volume vol0
