Abstract :
The storage stack in an operating system faces a number of dependability threats. The importance of keeping users´ data safe makes this area particularly worth investigating. We briefly describe the main threats (disk device failures, whole-system failures, software bugs, and memory corruption), and outline the Loris storage stack that we developed previously. We then present an integrated approach that combines several techniques to protect the Loris storage stack against these dependability threats, all the way from the disk driver layer to the virtual file system (VFS) layer.
