ReadWriteOnce -> single NODE access
ReadWriteOncePod -> single POD access
From doc:
How ReadWriteOncePod is different than the ReadWriteOnce access mode?
The ReadWriteOnce access mode restricts volume access to a single node, which means it is possible for multiple pods on the same node to read from and write to the same volume. This could potentially be a major problem for some applications, especially if they require at most one writer for data safety guarantees.
With ReadWriteOncePod these issues go away. Set the access mode on your PVC, and Kubernetes guarantees that only a single pod has access.

Thanks for the documentation.
So, should I edit something in my sketchnote? ;-)
