    摘要: Techniques for implementing an adaptive data access error handling policy are disclosed. In one particular exemplary embodiment, the technique may be realized as a system comprising a shared storage device communicatively coupled to a network, and a computer cluster communicatively coupled to the network, the computer cluster comprising a plurality of nodes each mounting a shared file system thereon, a first node of the plurality of nodes to send a data access request to the shared storage device, to identify a data access error associated with the data access request, and to determine whether to permit access to the shared file system based on the data access error being a local data access error or a global data access error.

    摘要: A method for implementing selective file system caching. The method includes receiving I/O requests from an application and comparing each of the I/O requests with a configurable cache map, wherein the configurable cache map controls a selective caching based on an I/O type and a file type. Each of the I/O requests are processed to render caching decisions based on the configurable cache map. Selective caching is then implemented on each of the I/O requests in accordance with the caching decisions.

    摘要: A method, system, computer-readable storage medium and apparatus for balanced and consistent placement of resource management responsibilities within a multi-computer environment, such as a cluster, that are both scalable and make efficient use of cluster resources are provided. Embodiments reduce the time that a cluster is unavailable due to redistribution of resource management responsibilities by reducing the amount of redistribution of those responsibilities among the surviving cluster members. Embodiments further provide redistribution of resource management responsibilities based upon relative capabilities of the remaining cluster nodes.

    摘要: A system and method for replicating a set of files from a source computer system to a target computer system are described. The underlying extent structure of the files may be preserved. For example, if an original file on the source computer system has a particular number of extents then the copy of the file created on the target computer system may have the same number of extents, where each respective extent in the copy represents the same byte range of the file as its corresponding extent in the original file. The file systems employed on the source computer system and the target computer system may support different extent types. The extent types of the original files stored on the source computer system may be preserved in the copies of the files on the target computer system.
