Procedures Infra can take to clean up disk space

Various places/commands where if needed, extra that can reclaim disk space can be reclaimed.

$JENKINS_HOME/jenkins-slave/maven-repositoriesfind . -atime +15 -delete42GB / 20GB?How is this different to .m2/repository - are we duplicating here?

$JENKINS_HOME/jenkins-slave/workspace/trafficcontrol-PR_ws-space*rm rf .350MB x 6750 directoriesThis scenario can sometimes be missed due to the directories being small in size - 350MB - but with we have thousands of such directories adds that add up to over 100GB!

Procedures Projects can take to clean up disk space

Projects can help themselves and Infra by following taking some basic steps to help
clean up their jobs after them themselves on the build nodes.


  1. Use a ./tmp dir in your jobs workspace. That way it gets cleaned up when job workspaces expire.
  2. Configure your jobs to wipe workspaces on start or finish.
  3. Configure your jobs to only keep 5 or 10 previous builds.
  4. Configure your jobs to only keep 5 or 10 previous artifacts.
