Appl. No.:

12/113170

Inventors:

Prashant Pogde - Santa Clara CA, US
Manish M. Agarwal - Fremont CA, US

Assignee:

NetApp, Inc. - Sunnyvale CA

International Classification:

G06F 12/08
G06F 12/12
G06F 12/14

US Classification:

707825, 707822, 707828, 707829

Abstract:

A new approach to support efficient management of directory quotas for a file system is proposed. The approach adopts bitmasks for files and directories in a file system, and transforms the problem of maintaining and traversing complicated file system data structures into a simple bitmask comparison and an associated lookup. It applies to files and directories under CIFS, NFS, other network file systems and local file systems and moves the costly operations of traversing the file system from file operations to administrative operation of switching the quotas on and off, which is infrequent and do not have the performance requirements of regular file operations.

International Classification:

G06F 17/30

US Classification:

707711, 707741, 707716

Abstract:

Embodiments of the present invention provide a novel technique for maintaining directory-based quota, for performing directory notification to a client system, and performing other such operations by efficiently finding ancestral directory associations on a server system without performing multiple accesses to data structures associated with the directory associations. Since data structures do not need to be accessed multiple times, performance of the server system can be improved.

International Classification:

G06F 7/00
G06F 17/30

US Classification:

707741

Abstract:

Method and system is provided for managing metadata for a plurality of data containers that are stored at one or more storage volumes in a storage system. The metadata is collected from one or more storage volumes and then provided to a catalog module. The catalog module pre-processes the metadata and then generates a searchable data structure. The searchable data structure may then be used to respond to a user request for information regarding the storage system.

US Classification:

707741

Abstract:

Method and system is provided for managing metadata for a plurality of data containers that are stored at one or more storage volumes in a clustered storage system. The metadata is collected from one or more storage volumes and then provided to a catalog module. The catalog module pre-processes the metadata and then generates a searchable data structure. The searchable data structure may then be used to respond to a user request for information regarding the storage system.

Appl. No.:

10/627258

Inventors:

Paul L. Popelka - Cupertino CA, US
Manish M. Agarwal - Mountain View CA, US

Assignee:

Symantec Operating Corporation - Mountain View CA

International Classification:

G06F 17/30
G06F 15/173
G06F 11/00

US Classification:

707 8, 714 4, 709225

Abstract:

A computer accessible medium may be encoded with a plurality of instructions which, when executed in a first node of a plurality of nodes in response to a fail over of a first service group of a plurality of service groups from a second node of the plurality of nodes, initiate lock recovery for locks on one or more filesystems included in the service group. Locks on one or more filesystems in a second service group of the plurality of service groups may be maintained during a time period that locks in the first service group are recovered. The lock recovery may be initiated using a first client list of a plurality of client lists, wherein the first client list is included in the first service group and identifies clients having at least one lock on a filesystem included in the first service group. During the fail over of a service group, lock services may not be interrupted for other service groups on any of the nodes.

International Classification:

H04L 12/707
H04L 29/08

Abstract:

A machine has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to receive data from a data source that continuously generates records, selectively identify conditions within the data that satisfy specified rules, and report the conditions prior to routing the data to a message system node forming a segment of a distributed transaction log with messages persisted in non-volatile memory and replicated within a cluster of nodes.
