A good first step is always to check out the FAQ and documentation. Otherwise, many members of the community hang out on irc and are happy to answer questions. We are spread out over many timezones though (and have day jobs), so you may need to be patient when waiting for a reply.
Extended or complex issues might be better sent to the relevant mailing list(s) (you'll need to subscribe in order to send messages). Don't worry if you pick the wrong one, many of us are on multiple lists and someone will suggest a more appropriate forum if necessary.
People new to the project, or Open Source generally, are encouraged to read Getting Answers by Mike Ash from Rogue Amoeba. It provides some very good tips on effective communication with groups such as this one. Following the advice it contains will greatly increase the chance of a quick and helpful reply.
Bugs and other problems can also be reported via Bugzilla.
The development of most of the ClusterLabs-related projects take place as part of the ClusterLabs organization at Github, and the source code and issue trackers for these projects can be found there.
If you find this project useful, you may want to consider supporting its future development. There are a number of ways to support the project (in no particular order):
- Spread the word
- Help others on the mailing list
- Contribute patches
- Contribute documentation and examples or update the wiki
- Use it on Red Hat Enterprise Linux or SUSE Linux Enterprise Server. Red Hat and SuSE fund the majority of our work, using it on their products helps ensure they continue to see it as a priority.
