Abstract: A technique provides efficient management of policies for objects of a distributed storage architecture configured to service storage requests issued by one or more clients of a storage cluster. The objects may include volumes for storing data served by storage nodes of the cluster and the policies may include quality of service (QoS) policies. The technique enables dynamic grouping of the volumes as management domains and applying attributes, such as performance settings of the QoS policies, to the management domains. A group of volumes may be organized as a management domain and a QoS policy may be applied to the domain. If membership of the management domain is modified, the QoS policy is automatically applied to the added volume or stripped from the removed volume. If a performance setting of the policy is modified, the modification is atomically applied and propagated to each volume of the management domain.

Abstract: Disclosed are systems, computer-readable mediums, and methods for transforming data in a file system. As part of a recycling process, a determination is made that transformations should be attempted. A data block is determined to be in use by at least one user of the storage system. If a transformation should be attempted on the data block is determined. Parameters associated with the performance of the file system can be used in this determination. A type of transformation to be done is determined. The data block is transformed based upon the selected transformation. The transformed data block is written to the storage system. As part of the recycling process, the transformation requires no additional input/output requests.
