4.11. Dépannage de KMM

Lors du dépannage des problèmes d'installation de KMM, vous pouvez surveiller les journaux afin de déterminer à quelle étape les problèmes surviennent. Vous pouvez ensuite récupérer les données de diagnostic correspondant à cette étape.

4.11.1. Utilisation de l’outil must-gather

La commande oc adm must-gather est la méthode préférée pour collecter un paquet d'assistance et fournir des informations de débogage à l'assistance de Red Hat. Collectez des informations spécifiques en exécutant la commande avec les arguments appropriés, comme décrit dans les sections suivantes.

4.11.1.1. Collecte de données pour la KMM

Procédure

  1. Rassembler les données pour le gestionnaire du contrôleur de l'opérateur KMM :

    1. Définir la variable MUST_GATHER_IMAGE:

      Copy to Clipboard Toggle word wrap 
      $ export MUST_GATHER_IMAGE=$(oc get deployment -n openshift-kmm kmm-operator-controller-manager -ojsonpath='{.spec.template.spec.containers[?(@.name=="manager")].env[?(@.name=="RELATED_IMAGES_MUST_GATHER")].value}')
      Note

      Utilisez le commutateur -n <namespace> pour spécifier un espace de noms si vous avez installé KMM dans un espace de noms personnalisé.

    2. Exécutez l'outil must-gather:

      Copy to Clipboard Toggle word wrap 
      $ oc adm must-gather --image="${MUST_GATHER_IMAGE}" -- /usr/bin/gather

  2. Consulter les journaux de l'opérateur :

    Copy to Clipboard Toggle word wrap 
    $ oc logs -fn openshift-kmm deployments/kmm-operator-controller-manager
