PowerFlex

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

Update Driver from v2.2 to v2.3 using Helm

Steps

  1. Run git clone -b v2.3.0 https://github.com/dell/csi-powerflex.git to clone the git repository and get the v2.3.0 driver.
  2. You need to create config.yaml with the configuration of your system. Check this section in installation documentation: Install the Driver
  3. Update values 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 --upgrade.

NOTE:

  • 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 --upgrade.

  • The logging configuration from v1.5 will not work in v2.1, since the log configuration parameters are now set in the values.yaml file located at helm/csi-vxflexos/values.yaml. Please set the logging configuration parameters in the values.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 CSI Operator:

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