摘要： A mechanism is provided for cross-allocated block repair in a mounted file system. A set of cross-allocated blocks are identified from a plurality of blocks within an inode of the mounted file system, based on a corresponding bit associated with each cross-allocated block in a duplicated block information bitmap being in a first identified state. The set of cross-allocated blocks are repaired using a user-defined repair process. Then one or more of the set of cross-allocated blocks are deallocated based on results of the user-defined repair process.

摘要： In one embodiment, a method for providing parallel reading in a clustered file system having cache storage includes using an owner gateway node to read data for a fileset, determining whether to utilize other gateway nodes to handle a portion of read traffic for the fileset, selecting a set of eligible gateway nodes based on: a current internal workload, a network workload, and recent performance history data regarding workload distribution across the other gateway nodes, assigning and defining a size for read task items for each gateway node in the set based on a current dynamic profile of each gateway node in the set, providing in-memory and/or input/output resources at each gateway node in the set to handle assigned read task items, and distributing workload to the set of eligible gateway nodes according to the size for the assigned read task items for each gateway node in the set.

摘要： A computer determines a degree of information duplication between at least two files included in an original pre-fetch list. The computer generates a re-ordered pre-fetch list by re-ordering the files included in the original pre-fetch list. The re-ordering is based, at least in part, on the degree of information duplication between the two files included in the original pre-fetch list. The files included in the original pre-fetch list are re-ordered by grouping files containing higher degrees of duplicate information closer together in the re-ordered pre-fetch list.

摘要： In one embodiment, a system is configured to use an owner GW node to write data for a first fileset and determine whether to utilize one or more other GW nodes to handle at least a portion of write traffic for the first fileset, select a set of eligible GW nodes, assign and define a size for one or more write task items for each GW node based on a current dynamic profile of each GW node, provide and/or ensure availability to in-memory and/or I/O resources at each GW node in the set of eligible GW nodes to handle one or more assigned write task items, and distribute workload to the set of eligible GW nodes according to the size for each of the one or more assigned write task items for each individual GW node in the set of eligible GW nodes.

摘要： In one embodiment, a method includes determining each gateway (GW) node in a clustered file system eligible to process read tasks and constructing a GW node list of all eligible GW nodes, determining a home node that corresponds to each GW node in the list, creating individual home node GW lists for each home node, with each home node GW list including a set of GW nodes which share a same home node, determining a peer GW eligibility value for each GW node, determining a GW node having a highest eligibility value for each home node, removing all other GW nodes which do not have the highest eligibility value for each home node from the list, assigning and defining a size for read task items for each GW node in the list, and distributing workload to each GW node in the list according to sizes of the read task items.

摘要： A mechanism is provided in a data processing system for de-duplication aware secure delete. Responsive to receiving a secure delete request for a file, the mechanism identifies a list of file blocks to be securely deleted from a physical disk device. Responsive to determining at least one virtual block of another file refers to a given disk block corresponding to a file block in the list, the mechanism copies the given disk block to generate a copied disk block in the physical disk device and updates a pointer of the at least one virtual block to refer to the copied disk block. The mechanism writes a secure delete pattern for each file block in the list of file blocks to a disk block in the physical disk device without performing de-duplication processing.
