摘要： A method performed by a data storage apparatus of maintaining filesystem object attributes in connection with a plurality of drivers is provided. Each driver of the plurality is configured to operate on a respective set of filesystem objects. The method includes (a) for each driver of the plurality, creating a respective driver-specific storage volume; (b) storing, within each driver-specific storage volume, attributes specific to respective filesystem objects operated on by the driver of that driver-specific storage volume; and (c) while operating a particular driver of the plurality on a particular filesystem object, using values of the stored attributes specific to that particular filesystem object operated on by that particular driver. An apparatus, system, and computer program product for performing a similar method are also provided.
