Volume Stats
Volume stats are used by the different schedulers for the drivers to providea report on their current state of the backend. The following should beprovided by a driver.
- driver_version
- free_capacity_gb
- reserved_percentage
- storage_protocol
- total_capacity_gb
- vendor_name
- volume_backend_name
NOTE: If the driver is unable to provide a value for free_capacity_gb ortotal_capacity_gb, keywords can be provided instead. Please use 'unknown' ifthe array cannot report the value or 'infinite' if the array has no upperlimit.
