I want to learn more about Xtreemfs source code, such as OSD、Flease

[bg_...@aliyun.com]

I am a student and I want to learn Xtreemfs in depth and understand his source code and working mechanism. Debugging the source code on IDEA, I really can't learn the key points, so I hope you can help me and guide me!

Thank you for your precious time

Hi,

as you noticed, XtreemFS is not a trivial project. In fact, many researchers have contributed, and as a result the source code may not be of a quality you might expect from say, enterprise-level software.

I recommend consulting the user guide: https://github.com/xtreemfs/xtreemfs/blob/master/doc/xtreemfs-userguide/xtfs-guide.pdf

You can learn from the init scripts how to start the services: https://github.com/xtreemfs/xtreemfs/blob/master/etc/init.d/xtreemfs-service.template and https://github.com/xtreemfs/xtreemfs/blob/master/etc/init.d/generate_initd_scripts.sh

They will invoke main classes in java/xtreemfs-servers (DIR, MRC, OSD), which you can then trace.

The cpp/ directory contains the client and fuse mount, which communicate via RPC/protobuf with the server components.

For flease consider the paper available, along with plenty of other documentation, on the XtreemFS website: http://www.xtreemfs.org/publications/flease_paper_ipdps.pdf

If you encounter anything specific, please come back with more questions. As for this general inquiry, the above is all that I can give you, as a general introduction to the source code would take too much time.

Thanks for understanding and good luck with your studies!

Cheers

Robert
