Jenkins is an open-source automation server that enables developers to build, test, and deploy their software reliably. It is a key tool in continuous integration and continuous delivery (CI/CD) pipelines, allowing teams to automate various stages of software development.
One common issue Jenkins users encounter is the failure of jobs due to insufficient disk space. This problem manifests as errors in the console output, indicating that Jenkins cannot proceed with the build process.
The error code JENKINS-408 typically points to a situation where the Jenkins server's disk space is fully utilized. This can occur due to the accumulation of old builds, logs, and other artifacts that consume storage over time.
When disk space is exhausted, Jenkins cannot create new build directories or store build artifacts, leading to job failures and potential disruptions in the CI/CD pipeline.
To address the disk space problem, follow these actionable steps:
Navigate to the Jenkins dashboard and identify jobs with a large number of builds. Consider deleting old builds that are no longer needed. You can also configure Jenkins to automatically discard old builds by setting a build retention policy.
Manage Jenkins > Configure System > Discard Old Builds
If cleaning up old builds is insufficient, consider increasing the disk space allocated to the Jenkins server. This may involve resizing the disk on a virtual machine or adding additional storage.
In some cases, it may be beneficial to configure Jenkins to store build artifacts and logs on a different disk or network-attached storage (NAS). This can be done by modifying the Jenkins configuration file to point to a new storage path.
JENKINS_HOME=/path/to/new/storage
