High FabricPool latency while promoting data back to performance tier
Applies to
- ONTAP 9
- FabricPool
- AWS
Issue
- Reads to tiered data fail and high latency is observed:
EMS:
[Node-01: OscHighPriThreadPool: wafl.ca.latency.threshold:notice]: Measured latency from cloud (104748 msec) more than threshold (5000 msec) (aggregate: "aggr_data1_01", aggregate uuid: "AGGR-UUID", object store: "ObjectStore")
- FabricPool read latency is a function of connectivity to the cloud tier
