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

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.
