As can be seen from the last lines of the previous file, there is the possibility to choose which node to draw the storage from, thanks to nodeAffinity. If this parameter is omitted, the cluster chooses. Kubernetes usually does not allow you to use the master for this purpose and, by the way, it is not a good architectural practice. The ideal is to create a new VM, with a generous hard disk and lacking in RAM/CPU, and combine it with the cluster. This node should only be used for data archiving and at the same time prevent workflows running on it. To obtain this result it is sufficient to add a taint on the node (reference).
