The FTP mirrors are fairly complex, especially when it comes to the way data is kept in sync and monitored. There are many scripts that are scattered about that makes the magic happen. Hopefully this documentation reveals the truth behind the magic.
The nature of our system allows some flexibility to the services that we can offer. We can serve as the master mirror for small projects, but also as a part of a large project’s mirror infrastructure. Each set of data is referred to as a ‘tree’; each project may have one or more trees.
This project has been tightly integrated into the OSL mirror infrastructure and has a lot of hard coded references to hosts, paths and other bits.
As it stands now, the system is currently deployed using the OSL internal CFEngine configuration management system. Documentation will be updated to reflect how it should be installed externally.
Most of the files reside in /data/mirror on the nodes while some scripts are located in /usr/local/sbin. In addition there are other services such as xinetd, bwbar, etc that need to be configured outside these directories or the current repository.
Currently there are three servers in the system:
The scripts used to manage the servers fall into several categories:
Some of these links are restricted to OSL only networks currently.
