The manual is open to contributions if you find problems therein.  Please see:


> I also have difficulty finding all the information I want in a single location and in a logical fashon.  These aren't new issues and blight all documentation, but having the definitive source in a wiki might open it up to more transparency, greater use and thus, ultimately, being kept up to date, even if its by others outside Intel.

I'd be thrilled if there were contributors to the manual outside of Intel.  IMHO, users who are not intimately familiar with Lustre are the best people to know when the manual isn't clear or is missing information.  I personally don't read the manual very often, though I do reference it on occasion.  When I find something wrong or outdated, I submit a patch, and it generally is landed quickly.

> I'd also like a section where people can post their experiences and solutions.  For example, in recent times, we have battled bad interactions with ZFS+lustre which lead to poor performance and ZFS corruption.  While we have now tuned both lustre and zfs and the bugs have mostly been fixed, the learnings, trouble shooting methods etc. should be preserved and might assist others in the future diagnose tricky problems.

Stack overflow for Lustre?  I've been wondering about some kind of Q&A forum for Lustre for a while.  This would be a great project to propose to OpenSFS to be hosted on the lustre.org site (Intel does not manage that site).  I suspect there are numerous engines available for this already, and it just needs someone interested and/or knowledgeable enough to pick an engine and get it installed there.

Cheers, Andreas
