摘要： According to this invention, a computer system which provides a client node with a file system mounted into a virtual namespace, comprising: at least one file server which provides the file system; a root node which mounts the file system provided by the file server into the virtual namespace; and a network which couples the file server and the root node. The root node has an interface coupled to the network, a processor coupled to the interface, and a memory coupled to the processor. The root node is configured to: obtain access information set to a directory above a point in the virtual namespace at which the file system is to be mounted when mounting the file system into the virtual namespace; judge whether the obtained access information is to be inherited; and set, to the file system to be mounted, the obtained access information that is to be inherited.

摘要： A storage system configured to be applied to a broad range of access forms to the file and improve performance of file access control processing. The storage system may store a part of the access control information of a variable size in the basic attribute area of the file, and store the storage format information in the basic attribute area of the file or in the file system metadata area. At the time of processing the access to the file, with reference to the storage format information, the storage system may decode a part of the access control information into an access mask bit string as needed, and perform the preceding access control processing.

摘要： A computer apparatus which integrates at least two or more services of user management domains has a processor, a memory and an interface. The processor receives an access request, specifies an access source domain, specifies an access target domain, and judges whether the specified access source domain matches the specified access target domain. If the access source domain is different from the access target domain, the processor extracts a user ID of the specified access source domain from the received access request, and refers to ID conversion information indicating correspondence of user IDs between the user management domains whose services are integrated to convert the extracted user ID of the access source domain into a user ID of the specified access target domain. Thus, loads of configuration at the time of service integration are reduced.

摘要： In the prior art clone creating technique of a file, a management table of a snapshot and the file was created when creating the clone file, so that a considerable amount of creation time for creating the clone file and storage capacity was required. In order to solve the problems of the prior art, the present invention provides a system wherein if a request to create a clone of a file is received, a differential file is created while inhibiting update of the file, and update data is written to the differential file. Further, when a first update request is received to the differential file after creating the differential file, a management table is created. According to the invention, a large amount of clone files can be created speedily.

摘要： Each time the file access request is received, it is discriminated whether there is an ACL which corresponds with the file system of the type following the switching in the file designated by the file access request. In cases where the judgment result is that there is no such ACL, an ACL which corresponds with the file system of the type following the switching is generated on the basis of an ACL which corresponds with the file system of the type prior to the switching which is associated with the designated file, and the ACL thus generated is used to control access in accordance with the received file access request.

摘要： Problem: Providing a storage system which can be applied to a broad range of access forms to the file and, at the same time, in which the performance of file access control processing is improved. Solution: The storage system stores a part of the access control information of a variable size in the basic attribute area of the file, and stores the storage format information in the basic attribute area of the file or in the file system metadata area. At the time of processing the access to the file, with reference to the storage format information, the storage system decodes a part of the access control information into an access mask bit string as needed, and performs the preceding access control processing. If whether access is permitted or not can be determined through the preceding access control processing, the access control processing is performed while, whether access is permitted or not cannot be determined, performs the access control processing based on the extended attribute information.FigureFIG. 7
