Abstract: In one example, a request for storage of an extended attribute (EA) of a file system object is received. A storage location for the EA is determined from a plurality of storage locations, based on one or more characteristics of the EA, the plurality of storage locations including an inode, a first storage file accessible by a first B+ tree, and a second storage file accessible by a second B+ tree. The EA is accordingly stored in the determined storage location.

Abstract: A request to create a domain is received. The request is associated with a configuration parameter. The domain is indicative of a storage device comprising at least one volume for storing data pertaining to a file system (FS). Further, based on the configuration parameter, a configuration file set is created within the domain. The configuration file set is activated to load data structures corresponding to the configuration file set in a memory. The activation is based on a command received from an upper layer to perform an action on the configuration file set. Furthermore, configuration data is stored within the configuration file set when the action is performed on the configuration file set.

Abstract: Embodiments of the present invention provide a computer system, comprising at least two logical partitions, each partition having allocated computing resources, wherein the computing resources allocated to a first partition include memory storing a file system accessible by processes executing in the first partition; and a partition resource allocator, wherein the partition resource allocator is arranged to migrate the memory storing the file system from the first partition to a second partition, such that the file system is accessible by processes executing in the second partition.
