Methods and apparatuses for searching metadata are described herein. In one embodiment, an example of a process for search metadata includes, hut is not limited to, in response to a search query for metadata stored in one or more of metadata stores, the search query is partitioned into multiple search query segments. Thereafter, searches corresponding to the search query segments are performed, where each search is performed independently within the one or more metadata stores. Other methods and apparatuses are also described.

Method and apparatus for searching metadata

In one embodiment, in response to a request for searching a file stored in a first directory, a first lookup is performed by a virtual file system in a first file system to locate the file. The virtual file system traverses from the first directory back to a mount point of the first file system to recreate a search path from the mount point to the first directory. The virtual file system performs a second lookup in a second directory of a second file system that is associated with the mount point to locate the file in the second file system, where second directory is identified by the recreated search path.

Method for identifying corresponding directories in a union-mounted file system

A method and apparatus for sharing resources in a network environment. An application running on a client can access a resource on a remote computer by submitting a request via an Internet browser. The request is analyzed, converted to proper format and is transferred over the network lines to a server that can satisfy the request. For security reasons, an application may not be authorized to submit a request directly to a server on the Internet. If a requesting application has a trusted status, then its request for connecting to the server is granted. If a request submitted by an application to a server is denied, then a server that entrusts the application is identified, and the request is submitted to that server. A program code called a &ldquo;servlet&rdquo; is implemented on that server to accept the requests submitted by a trusted application. The submitted requests are analyzed by the servlet and are forwarded to a resource server that can satisfy the requests. A response from the resource server is routed through the servlet back to the requesting application.

Resource sharing on the internet via the HTTP

A method and apparatus for sharing resources in a network environment. Typically, a computer linked to the Internet may have resources or may provide services, that are usable by other computers. A user, using one or more embodiments of the invention, can access those resources or services as if they were locally situated. An application running on a client can access a resource on a remote computer by submitting a request via an Internet browser. The request is analyzed, converted to proper format and is transferred over the network lines to a server that can satisfy the request. For security reasons, an application may not be authorized to submit a request directly to a server on the Internet. For example, limitations have been implemented that prohibit a requesting application from obtaining access to resources of a server computer unless that application is a trusted application. If a requesting application has a trusted status, then its request for connecting to the server is granted. If a request submitted by an application to a server is denied, then a server that entrusts the application is identified, and the request is submitted to that server. A program code called a &ldquo;servlet&rdquo; is implemented on that server to accept the requests submitted by a trusted application. The submitted requests are analyzed by the servlet and are forwarded to a resource server that can satisfy the requests. A response from the resource server is routed through the servlet back to the requesting application.

A variety of methods and apparatus are taught for providing dynamic distributed file system client authentication. One method for providing dynamic distributed file system client authentication within a distributed file system computing environment includes the steps of receiving an NFS request from an NFS client, determining whether the NFS client has an access status sufficient to perform the NFS request, and performing the NFS request when the NFS client has sufficient access status. In some embodiments, the NFS request includes a file handle representing a given file system available on the server computer system and a file operation to be performed upon the given file system. A server computer in accordance with one embodiment of the present invention is operable to provide dynamic NFS client authentication. The server computer includes a CPU, a RAM accessible by the CPU, a ROM accessible by the CPU, a network I/O port coupled with the CPU, a mass storage device accessible by the CPU, and a kernel implemented on the server computer. In addition, the server computer implements a dynamic NFS client authentication service operable to receive an NFS request from an NFS client and to authenticate the NFS client in relation to the NFS request. The dynamic NFS client authentication service considers factors such as time, date, identity of the NFS client, a nature of the NFS request, and a current status of a resource upon which the NFS request operates.
