Issue

  • QoS throttling workload well short of IOPS limit_rate.
  • QoS throttling kicking in long before the stated workload limits.
  • Very large data access latency is observed even without much IOPs
  • QoS throttling kicking in long before the stated workload limits.
  • Multiple seconds of latency for workloads that are not near their QoS cluster limit and the reason could be seen as QoS limit.
  • QoS can even hang resulting in very large data access latency.
