What steps did you take and what happened:
[A clear and concise description of what the bug is, and what commands you ran.]

1. Created a new GKE cluster and labeled each node with openebs.io/nodeid and a distinct value
2. Installed the chart
3. Noticed errors in the plugin logs that it couldn't find a node by the name
