I guided to use the /storage/aggregates/{uuid} REST API endpoint, specifically the space.block_storage.used field, to determine their block storage usage (total allocated capacity within an aggregate). However, they reported that the space.block_storage.used value fluctuates slightly even when no volume expansion, creation, or writes to the storage are occurring.
Does the space.block_storage.used value include not only the space consumed by the user's data, but also metadata and information related to scheduled snapshots?
And, if metadata and snapshot information are included in space.block_storage.used, which field should be referenced to obtain only the explicitly allocated space used by the customer, excluding metadata and snapshots?
