Quick question. I'm reviewing the IOPS for my CSV, and im confused about the Cluster CSVFS\Reads/sec counter. I aligned Physical Disk\Disk Reads/sec (for the CSV disk) with Cluster CSV File System\IO Reads/sec and Cluster CSVFS\Reads/sec. The first two align (shows roughly the same value), but Cluster CSVFS\Reads/sec is way off the chart. Which is the real number? My assumption is that the Cluster CSVFS\Reads/sec value is inaccurate, or does not reflect disk IO (aka IOPS).

You can try running the benchmark on your CSV with fio and compare its output with metrics. It might help you identifying the accurate counter. I've been doing benchmarks and Physical disk counters showing the same numbers to fio output. – Stuka Jul 12 '20 at 15:40

this is the documentation from microsoft for CSV: https://techcommunity.microsoft.com/t5/failover-clustering/cluster-shared-volume-performance-counters/ba-p/371980
your counter show empty becouse, your node isnt the coordinator.
