Log-Based Directory Resolution in the Coda File System

semantic knowledge all concurrent partitionedAbstract updates to an object must be treated as conflicting, andOptimistic replication is an important technique for merged manually by the user. Manual resolution isachieving high availability in distributed file systems. A undesirable because it reduces the overall usability of thekey problem in optimistic replication is using semantic knowledge of objects to resolve concurrent updates from system. multiple partitions. In this paper, we describe how the Coda File System resolves partitioned updates to An extremely important object, with known semantics, in directories. The central result of our work is that logging of Unix file systems is a directory. We refer to the process of updates is a simple yet efficient and powerful technique for examining replicas of a directory, deducing the set ofdirectory resolution in Unix file systems. Measurements partitioned updates and merging them using Unixfrom our implementation show that the time for ...
