Plugin: openmediavault-diskstats 5.0.3-1
All disks attached to my new LSI 9200-8e SAS Controller in IT mode have no graphs available (frown faced) in Disk I/O.
Refreshing the graphs and using OMF First Aid to to check the RRD Databases doesn't fix it.
Edit:
I purged and reinstalled the plugin. AOK now.
