PowerFlex

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

Update Driver from v2.7.1 to v2.8 using Helm

Steps

Run git clone -b v2.8.0 https://github.com/dell/csi-powerflex.git to clone the git repository and get the v2.8.0 driver.
You need to create secret.yaml with the configuration of your system. Check this section in installation documentation: Install the Driver
Update myvalues file as needed.

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 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.
