Title: Manifesting Reliability Issues in Storage Systems
Abstract: In recent times, there has been a rapid growth in the amount of data generated and to retrieve information quickly. Therefore, we expect storage systems to store data reliably and provide desired performance. On one hand, reliability in storage systems is achieved by employing recovery procedures to mitigate the effects of system failures. Yet, no existing works have studied the impact of system failures on recovery procedures. On the other, performance is achieved by employing new storage technologies (such as Non-Volatile Memory devices). But accommodating new storage devices requires modifying the storage stack, and therefore resulting in system failures (due to bugs in implementation, etc.). In my presentation, I will showcase our method on manifesting reliability issues in recovery procedures and provide a simple method to mitigate these issues. In addition, I will also showcase the reliability issues induced by accommodating new Persistent Memory storage technology in Linux storage stack.
