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).
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.
