Issue

Some performance counters returned by the ListVolumeStatsByVolume API may retain their last non-zero values after all iSCSI sessions to a volume have been terminated.

Affected counters include:

  • actualIOPS
  • latencyUSec
  • volumeUtilization
  • clientQueueDepth

Under certain conditions, these statistics do not immediately return to zero after the volume is no longer connected to any initiator and no active I/O is occurring.
