Filesystem data integrity in a single system image environment |
摘要 |
A system for protection of filesystem data integrity within a computer cluster is provided. The system uses redundant data caches at client and server nodes within the computer cluster. Caching of filesystem data is controlled so that non-shared files are preferably cached at client nodes. This increases filesystem performance within the computer cluster and ensures that failures may not result in a loss of modified filesystem data without a corresponding loss to the process(es) accessing that data. Shared files are cached at the server node and a backup cache node. This protects modified filesystem data against any single node failure.
