Patent abstract
The reserves of a flexible volume and the aggregate which contains the flexible volume are “stacked”. When the flexible volume is created, a portion of the flexible volume having a capacity equal to or less than an unreserved portion of the flexible volume is guaranteed by the aggregate. When the flexible volume creates or modifies metadata, the flexible volume issues a request to the aggregate. The aggregate then issues a portion of the reserve of the aggregate to the flexible volume for storing the metadata.
