Observability

Upgrade Observability

The Observability module installed by the Dell CSM Operator can be updated like any Kubernetes resource.

• Modifying the existing driver and module installation directly via kubectl edit

  kubectl get <driver-object> -n <driver-namespace>
  

  For example - If the CSI PowerScale driver is installed then run this command to get the object name

  # Replace driver-namespace with the namespace where the CSI PowerScale driver is installed
  $ kubectl get csm -n <driver-namespace>
  

  use the object name in kubectl edit command.

  kubectl edit csm <driver-object>/<object-name> -n <driver-namespace>
  

  For example - If the object name is isilon then use the name as isilon

  # Replace object-name with the isilon
  kubectl edit csm isilon -n <driver-namespace>
  

• Modify the installation

  • Update the driver config version and image tag
  • Update the Observability config version, csm-topology image and the driver metrics images(e.g. for CSI PowerScale driver, the metrics driver image would be csm-metrics-powerscale)

NOTE:

• In observability module upgrade, only n-1 to n upgrade is supported, e.g. if the current observability version is v1.7.x, it can be upgraded to 1.8.x.
• Upgrade to csm-operator and csi-driver first which support the corresponding observability module version.
