Hi RobinHood developpers and users, I am studying with EDF the opportunity to deploy RobinHood on their HPC clusters running Lustre 2.12.
We are particularly interested on any feedback about: - The impact on filesystem performances of the activation of Lustre changelog with default event mask [0]? Does anyone has numbers to share? - The current state of Lustre PFL support? The last "RobinHood Project Update" slides available in the wiki from 2017 [1] say « no PFL support for now » but commit in 2019 mentions a « workaround to support PFL » [2]. I must admit I am not an experienced Lustre expert and I don't fully understand the comment « It only stores and handles the striping information of the last initialized component of a layout, which is likely the one suited for the current file size. » What are the caveats and the limits of the current workaround? - The roadmap for v4? I saw these slides from LAD'22 that mentions tests in 2023. Do you plan any release this year? Thank you in advance for any kind of answer!
