Final call for PAC participants given. Three people on the<br /> call volunteered. Contract wiki page is at:<br /> <br /> [http://wiki.opensfs.org/Contract_SFS-DEV-004]<br /> <br /> The Lustre Protocol Documentation project is under negotiation with Intel.<br /> A call for &quot;pre-PAC&quot; volunteers was communicated. The early PAC members<br /> will help Chris with the contract work.<br /> <br /> === Lustre&#039;s Future (and OpenSFS&#039;s role) ===<br /> <br /> Peter Bojanic revived discussion about Lustre testing from previous meetings.<br /> He made the suggestion that robust acceptance tests are more valueable than<br /> documentation.<br /> <br /> Chris suggested that, while testing is extremely valuable, documentation<br /> is arguably more valueable than testing because it informs all stages of the<br /> software development process including the tests that need to be created.<br /> <br /> Chris talked a bit a possible direction for OpenSFS to focus its effort: spend<br /> most new funds on tackling the long standing Lustre technical debt directly,<br /> mostly in the forms of documentation and code refactoring.<br /> <br /> Chris suggests that our current approach of trying to handle technical debt<br /> as a side effect of feature development is not dealing with the problem at<br /> an accepatable rate. Technical debt is also an area that individual vendors<br /> and other organizations are unlikely to tackle on their own. He suggests<br /> that OpenSFS should be the place where we can come together to take this<br /> necessary and challenging work.<br /> <br /> Peter Bojanic agreed that sales forces at vendor organizations tend to prioritize<br /> features over foundational work.<br /> <br /> Eric Barton wondered if it would be a good idea to address the design defficiencies<br /> in Lustre that make it less than tolerant of various forms of system failures.<br /> <br /> Chris thought that it would be very nice to do that, but making further changes<br /> to the Lustre protocol without having a documented protocol is asking for trouble for<br /> several reasons, including that the Lustre client code is now in the staging<br /> area of the Linux kernel. Maintaining protocol compatibility is already a weak point<br /> for Lustre, and is only going to get harder without protocol documentation.<br /> <br /> == Action Items ==<br /> <br /> * Chris to make mailing list for SFS-DEV-004 PAC members and related Intel personnel<br /> * Continue work on Lustre Protocol Documentation Project<br /> * Make wiki page listing Lustre Reviewers by topic area</div>
