PowerFlex

You can upgrade the CSI Driver for Dell PowerFlex using Helm or Dell CSM Operator.

Update Driver from v2.8.0 to v2.9.2 using Helm

Steps

1. Run git clone -b v2.9.2 https://github.com/dell/csi-powerflex.git to clone the git repository and get the v2.9.2 driver.
2. You need to create secret.yaml with the configuration of your system. Check this section in installation documentation: Install the Driver
3. Update myvalues file as needed.
4. Run the csi-install script with the option --upgrade by running:

   
   cd ../dell-csi-helm-installer && ./csi-install.sh --namespace vxflexos --values ./myvalues.yaml --helm-charts-version <version> --upgrade
   

NOTE:

• The parameter --helm-charts-version is optional and if you do not specify the flag, by default the csi-install.sh script will clone the version of the helm chart that is specified in the driver’s csi-install.sh file. If you wish to install the driver using a different version of the helm chart, you need to include this flag. Also, remember to delete the helm-charts repository present in the csi-powerflex directory if it was cloned before.

• If you are upgrading from a driver version that was installed using Helm v2, ensure that you install Helm3 before installing the driver.

• To update any installation parameter after the driver has been installed, change the myvalues.yaml file and run the install script with the option --upgrade, for example:

  
  ./csi-install.sh --namespace vxflexos --values ./myvalues.yaml --helm-charts-version <version> --upgrade
  

• The logging configuration from v1.5 will not work in v2.1, since the log configuration parameters are now set in the myvalues.yaml file located at dell-csi-helm-installer/myvalues.yaml. Please set the logging configuration parameters in the myvalues.yaml file.

• You cannot upgrade between drivers with different fsGroupPolicies. To check the current driver’s fsGroupPolicy, use this command:

   kubectl describe csidriver csi-vxflexos.dellemc.com
  

  and check the “Spec” section:

  ...
  Spec:
    Attach Required:     true
    Fs Group Policy:     ReadWriteOnceWithFSType
    Pod Info On Mount:   true
    Requires Republish:  false
    Storage Capacity:    false
  ...
  

Upgrade using Dell CSM Operator:

Note: Upgrading the Operator does not upgrade the CSI Driver.
