CONTAP-114158: Urgency is reported prematurely, on thinly-provisioned Flexgroups, when aggregate free space is less than the Flexgroup constituent size
Issue
- FlexGroup urgency is reported prematurely, which can potentially result in performance
degradation. - This is seen running the node level flexgroup show.
Example: Aggregate 1 on node 1 is full so the FlexGroup is full, increasing urgency above 0.
