	Simple "get your feet wet" coding projects are tracked in JIRA using the [https://jira.whamcloud.com/issues/?jql=project=LU%~~20%3D~~%20labels%~~20%3D%20easy%20and~~%20resolution~~%20%3D%20unresolved~~ '''easy''' keyword].

Simple "get your feet wet" coding projects are tracked in JIRA using the [https://jira.whamcloud.com/issues/?jql=project=LU%20AND%20labels=easy%20AND%20resolution=unresolved '''easy''' keyword].

	There are also a large number of issues tracked in the [https://scan.coverity.com/projects/lustre Lustre Coverity Project] that may be suitable for developers who want to become more familiar with the code. Note however, that some/many of the issues may not be as obvious to fix as they are presented by the Coverity tool (e.g. just initializing an uninitialized variable may not be the correct fix in some cases), but they will at least point you at code that needs to be fixed. If you are interested in working on some of these issues, please request access to the project.
