  • A Ffsck: the Fast File System Checker
    A ffsck: The Fast File System Checker AO MA, University of Wisconsin, Madison; Backup Recovery Systems Division, EMC Corporation CHRIS DRAGGA, ANDREA C. ARPACI-DUSSEAU, and REMZI H. ARPACI-DUSSEAU, University of Wisconsin, Madison MARSHALL KIRK McKUSICK, McKusick.com Crash failures, hardware errors, and file system bugs can corrupt file systems and cause data loss, despite the presence of journals and similar preventive techniques. While consistency checkers such as fsck can detect this corruption and restore a damaged image to a usable state, they are generally created as an afterthought, to be run only at rare intervals. Thus, checkers operate slowly, causing significant downtime for large scale storage systems when they are needed. We address this dilemma by treating the checker as a key component of the overall file system (and not merely a peripheral add-on). To this end, we present a modified ext3 file system, rext3, to directly support the fast file system checker, ffsck. The rext3 file system colocates and self-identifies its metadata blocks, removing the need for costly seeks and tree traversals during checking. These modifications to the file system allow ffsck to scan and repair the file system at rates approaching the full sequential bandwidth of the underlying device. In addition, we demonstrate that rext3 performs competitively with ext3 in most cases and exceeds it in handling random reads and large writes. Finally, we apply our principles to FFS, the default FreeBSD file system, and its checker, doing so in a lightweight fashion that preserves the file-system layout while still providing some of the gains in performance from ffsck.

  • Using MEMS-Based Storage Devices in Computer Systems
    Using MEMS-based storage devices in computer systems STEVEN W. SCHLOSSER May 2004 cmu-pdl-04-104 Dept. of Electrical and Computer Engineering Carnegie Mellon University Pittsburgh, PA 15213 A dissertation submitted to the graduate school in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Electrical and Computer Engineering. Thesis committee Gregory R. Ganger, Chair L. Richard Carley James C. Hoe Charles C. Morehouse, Hewlett-Packard Laboratories c 2004 Steven W. Schlosser i Keywords: MEMS-based storage, storage systems performance, database sys- tems, disk arrays To my family: my parents, Phil and Kathy; my sister, Jennifer; and my wife, Rachel. Abstract MEMS-based storage is an interesting new technology that promises to bring fast, non-volatile, mass data storage to computer systems. MEMS-based storage de- vices (MEMStores) themselves consist of several thousand read/write tips, anal- ogous to the read/write heads of a disk drive, which read and write data in a recording medium. This medium is coated on a moving rectangular surface that is positioned by a set of MEMS actuators. Access times are expected to be less than a millisecond with energy consumption 10{100× less than a low-power disk drive, while streaming bandwidth and volumetric density are expected to be around that of disk drives. This dissertation explores the use of MEMStores in computer systems, with a focus on whether systems can use existing abstractions and interfaces to incor- porate MEMStores effectively, or if they will have to change the way they access storage to benefit from MEMStores. If systems can use MEMStores in the same way that they use disk drives, it will be more likely that MEMStores will be adopted when they do become available.
