Poster is on display and will be presented at the poster pitch session.
Reproducibility is not only part of good scientific conduct but can also be used to check the health of the parallel Filesystems. We are revisiting our work in 2021 on using the IO500 benchmark to manage user expectations for I/O performance, and we found a couple of interesting changes in our BeeGFS filesystems. We can see how our hardware performance degrades compared to the performance data collected in 2021 and also facing puzzling changes in our metadata performance. In this work, we want to present our findings and discuss the next steps.
