In addition to the document Oleg has pointed out (which imho is probably
the best resource for a newcomer developer to start with), and the link
that Cory has provided which also includes documentation on some more
recent additions to the source (and is also a good source of information
for newcomers imo), some older HLDs can be found at
http://wiki.lustre.org/index.php/Architecture_-_Lustre_HLDs, and some newer
HLDs/architectural docs at
The Operations Manual is also quite useful i think, at
Added to all this, there are quite a few presentation slides and av
recordings from previous LUG/LAD or other events around the web that you
might find useful.
As Oleg has hinted, some of the information you may come across might be a
bit stale, as it applies to previous versions of the source, so please keep
in mind that whole subsystems that are referenced in a document you are
reading may have been completely replaced (by newer and better versions).
But don't let this be an issue, please ask here if something does not make
sense; people are usually quite keen to help.
