= Gathering data about your cluster for Red Hat Support
|
|
|
|
You can gather debugging information about your cluster by using the `oc adm must-gather` CLI command.
|
|
|
|
.Prerequisites
|
|
|
|
* Access to the cluster as a user with the `cluster-admin` role.
|
|
* The {product-title} CLI (`oc`) installed.
|
|
|
|
.Procedure
|
|
|
|
. Navigate to the directory where you want to store the `must-gather` data.
|
|
+
|
|
|
|
[NOTE]
|
|
====
|
|
If your cluster is in a disconnected environment, 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 in disconnected environments, you must import the default `must-gather` image as an image stream.
|
|
|
|
[source,terminal]
|
|
----
|
|
$ oc import-image is/must-gather -n openshift
|
|
----
|
|
====
|
|
|
|
. Run the `oc adm must-gather` command:
|
|
+
|
|
[source,terminal]
|
|
|
|
----
|
|
$ oc adm must-gather
|
|
----
|
|
+
|
|
[IMPORTANT]
|
|
====
|
|
If you are in a disconnected environment, use the `--image` flag as part of must-gather and point to the payload image.
|
|
====
|
|
+
|
|
[NOTE]
|
|
====
|
|
Because this command picks a random control plane node by default, the pod might be scheduled to a control plane node that is in the `NotReady` and `SchedulingDisabled` state.
|
|
====
|
|
|
|
.. 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.
|
|
+
|
|
[NOTE]
|
|
====
|
|
Contact Red Hat Support for the recommended resources to gather.
|
|
====
|
|
|
|
. 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:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ 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.
