Uninstall Portworx in ROSA

Using the Portworx Operator, you can efficiently uninstall Portworx from your clusters. This can be achieved by updating the StorageCluster object, and you have the option to either keep the data on your drives or wipe them completely.

• Uninstall: will remove the Kubernetes objects, Portworx systemctl service, /etc/pwx and /opt/pwx directories, and all traces of Portworx on the nodes. The drives will not be formatted and none the Portworx Metadata in the KVDB will be deleted. You may need to Uninstall Portworx if you installed Portworx in the wrong namespace.
• Uninstall and wipe: will remove all of the resources listed in the "Uninstall" procedure, and also removes (formats) all data from your disks permanently, including the Portworx metadata. You may want to perform an uninstall and wipe when you decommission a cluster.

Prerequisites

• A successfully deployed Portworx Operator on your cluster.

Uninstall Portworx

1. Enter the oc get command to display the name of your Portworx storage cluster and specify your namespace:

   oc get -n portworx storagecluster <storagecluster-name>

2. Enter the oc edit command to modify your storage cluster and specify your namespace:

   oc edit -n portworx storagecluster <storagecluster-name>

3. Modify your StorageCluster object, adding the deleteStrategy field with either the Uninstall or UninstallAndWipe type:

   • Uninstall Portworx only:

     apiVersion: core.libopenstorage.org/v1
     kind: StorageCluster
     metadata:
       name: portworx
       namespace: portworx
     spec:       
       deleteStrategy:
         type: Uninstall

   • Uninstall Portworx and wipe all drives:

     note

     Wipe operations remove all data from your disks permanently including the Portworx metadata, use caution when applying the DeleteStrategy spec.

     apiVersion: core.libopenstorage.org/v1
     kind: StorageCluster
     metadata:
       name: portworx
       namespace: portworx
     spec:       
       deleteStrategy:
         type: UninstallAndWipe

4. Enter the oc delete command, specifying the name of your StorageCluster object and specify your namespace:

   oc delete StorageCluster <your-storagecluster-name> -n portworx
   note

   This operation can take several minutes to complete.

5. Delete the operator:

oc delete deployment -n <px-namespace> portworx-operator
