Fault isolation and quick recovery in isolation file systems
L. Lu, Andrea Carol Arpaci-Dusseau, Remzi H. Arpaci-Dusseau · 2013
File systems do not properly isolate faults that occur within them. As a result, a single fault may affect multiple clients adversely, making the entire file system unavailable. We introduce a new file system abstraction, called file pod, to allow applications to manage failure and recovery polices explicitly for a group of files. Based on this abstraction, we propose the isolation file system, which provides fine-grained fault isolation and quick recovery. 1
