Servers? reintegration is a mode of file system operation that allows file servers to synchronize their data after network partitions. The reintegration design supports the main objectives of the disconnection-resilient file systems, which is to provide high available and reliable storage for files, and guarantees that file operations are executed in spite of concurrency and failures. In this paper, we show that server reintegration is efficient and practical by describing its design and implementation in Paradise File System. Moreover, we report on its performance evaluation using a cluster of workstations. Our results indicate clearly that our design exhibits a significant degree of automation and conflictfree mobile file system.
