3.2. Gathering data about your cluster for Red Hat Support

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

   注意

   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.

   注意

   If your cluster is using a restricted network, you must take additional steps. If your mirror registry has a trusted CA, you must first add the trusted CA to the cluster. For all clusters on restricted networks, you must import the default must-gather image as an image stream before you use 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.
