摘要	This work augments MINIX 3s failure-resilience mechanisms with novel disk-driver recovery strategies and guaranteed filesystem data integrity. We propose a flexible filter-driver framework that operates transparently to both the file system and the disk driver and enforces different protection strategies. The filter uses checksumming and mirroring in order to achieve end-toend integrity and provide hard guarantees for detection of silent data corruption and recovery of lost data. In addition, the filter uses semantic information about the drivers working in order to verify correct operation and proactively replace the driver if an anomaly is detected. We evaluated our design through a series of experiments on a prototype implementation: applicationlevel benchmarks show modest performance overhead of 0-28% and software-implemented fault-injection (SWIFI) testing demonstrates the filters ability to detect and transparently recover from both data-integrity problems and driver-protocol violations. © 2009 IEEE.
