Configuring persistent volumes

Edit online

Configure persistent volumes for application resources and logs before deploying PEM on OpenShift Container Platform.

About this task

PEM requires persistent volumes for storing application resources and logs. You must create and configure these volumes before deploying the Helm chart.

Procedure

  1. Create persistent volume for application resources

    When volumeClaims.resources.enabled is set to true, create a persistent volume with the following specifications:

    • Access mode: ReadWriteMany
    • Place the database driver JAR files in the mapped volume location
    • Place the SEAS JAR files in the mapped volume location
    • Place the MQ JAR files in the mapped volume location
  2. Create persistent volume for application logs

    When volumeClaims.logs.enabled is set to true, create a persistent volume with the following specifications:

    • Access mode: ReadWriteMany
    • Create required subfolders with 755 permissions for the following components:
      • PEM Portal
      • PEM 2.0
    • Ensure subfolders are accessible by the pemuser (id:1011) container
  3. Verify volume accessibility
    Ensure that the persistent volumes are accessible from inside the OCP cluster and that the access modes are correctly configured.
