Chapter 2. Gathering data about your cluster

Procedure

1. Navigate to the directory where you want to store the must-gather data.

2. Run the oc adm must-gather command:

   $ oc adm must-gather

   Note

   If this command fails, for example if you cannot schedule a Pod on your cluster, then use the oc adm inspect command to gather information for particular resources. Contact Red Hat Support for the recommended resources to gather.

   Note

   If your cluster is using a restricted network you must import the default must-gather image before running the oc adm must-gather command.

   $ oc import-image is/must-gather -n openshift

3. Create a compressed file from the must-gather directory that was just created in your working directory. For example, on a computer that uses a Linux operating system, run the following command:

   $ tar cvaf must-gather.tar.gz must-gather.local.5421342344627712289/ 1

   1

   Make sure to replace must-gather-local.5421342344627712289/ with the actual directory name.

4. Attach the compressed file to your support case on the Red Hat Customer Portal.
