+Successfully installed OpenEBS.

+Check the status by running: kubectl get pods -n {{ .Release.Namespace }}
+
+The default values will install both Local PV and Replicated PV. However,
+the Replicated PV will require additional configuration to be fuctional.
+The Local PV offers non-replicated local storage using 3 different storage
+backends i.e Hostpath, LVM and ZFS, while the Replicated PV provides one replicated highly-available
+storage backend i.e Mayastor.
