You can upgrade the CSI Driver for Dell PowerStore using Helm or Dell CSI Operator.
Update Driver from v2.2 to v2.3 using Helm
Note: While upgrading the driver via helm, controllerCount variable in myvalues.yaml can be at most one less than the number of worker nodes.
git clone -b v2.3.0 https://github.com/dell/csi-powerstore.gitto clone the git repository and get the driver.
helm/config.yamlfile and configure connection information for your PowerStore arrays changing the following parameters:
- endpoint: defines the full URL path to the PowerStore API.
- globalID: specifies what storage cluster the driver should use
- username, password: defines credentials for connecting to array.
- skipCertificateValidation: defines if we should use insecure connection or not.
- isDefault: defines if we should treat the current array as a default.
- blockProtocol: defines what transport protocol we should use (FC, ISCSI, NVMeTCP, None, or auto).
- nasName: defines what NAS should be used for NFS volumes.
- nfsAcls: (Optional) defines permissions - POSIX mode bits or NFSv4 ACLs, to be set on NFS target mount directory. NFSv4 ACls are supported for NFSv4 shares on NFSv4 enabled NAS servers only. POSIX ACLs are not supported and only POSIX mode bits are supported for NFSv3 shares.
Add more blocks similar to above for each PowerStore array if necessary.
(optional) create new storage classes using ones from
samples/storageclassfolder as an example and apply them to the Kubernetes cluster by running
kubectl create -f <path_to_storageclass_file>
Storage classes created by v1.4/v2.0/v2.1 driver will not be deleted, v2.2 driver will use default array to manage volumes provisioned with old storage classes. Thus, if you still have volumes provisioned by v1.4/v2.0/v2.1 in your cluster then be sure to include the same array you have used for the v1.4/v2.0/v2.1 driver and make it default in the
Create the secret by running
kubectl create secret generic powerstore-config -n csi-powerstore --from-file=config=secret.yaml
Copy the default values.yaml file
cp ./helm/csi-powerstore/values.yaml ./dell-csi-helm-installer/my-powerstore-settings.yamland update parameters as per the requirement.
csi-installscript with the option --upgrade by running:
./dell-csi-helm-installer/csi-install.sh --namespace csi-powerstore --values ./my-powerstore-settings.yaml --upgrade.
Upgrade using Dell CSI Operator:
While upgrading the driver via operator, replicas count in sample CR yaml can be at most one less than the number of worker nodes.
Upgrading the Operator does not upgrade the CSI Driver.
Please upgrade the Dell CSI Operator by following here.
Once the operator is upgraded, to upgrade the driver, refer here.
