Analyzing and Enhancing ArckFS: An Anecdotal Example of Benefits of Artifact Evaluation

2025

Abstract

We analyze and enhance Trio and ArckFS by Zhou et al. (SOSP 2023), high-performance NVM file system architecture and file system. A group of authors from KAIST initiated this study through a careful review of the paper and the released artifact, seeking to enhance the Trio work. Their analysis identifies (1) insufficient clarity in the paper on the handling of multi-inode operations, and (2) several implementation bugs in ArckFS that cause occasional operation failures or potential crash inconsistencies during inode creation. Through close collaboration between the KAIST and Trio authors, we have enhanced the Trio work. (1) We clarify a few relevant rules for ArckFS to handle multi-inode operations. (2) We develop patches for the identified bugs, which essentially maintain the performance claims made in the Trio paper. Our study highlights the crucial role of artifact evaluation in systems research and its potential benefits.

File system

In computing, a file system or filesystem (often abbreviated to fs) is a method and data structure that the operating system uses to control how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stopped and the next began, or where any piece of data was located when it was time to retrieve it. By separating the data into pieces and giving each piece a name, the data are easily isolated and identified.

Inode

The inode (index node) is a data structure in a that describes a object such as a or a directory. Each inode stores the attributes and disk block locations of the object's data. File-system object attributes may include metadata (times of last change, access, modification), as well as owner and data. A directory is a list of inodes with their assigned names. The list includes an entry for itself, its parent, and each of its children. There has been uncertainty on the Linux kernel mailing list about the reason for the "i" in "inode".

Clustered file system

A clustered file system is a which is shared by being simultaneously mounted on multiple servers. There are several approaches to clustering, most of which do not employ a clustered file system (only direct attached storage for each node). Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that spread data across multiple storage nodes, usually for redundancy or performance.
