Install an OpenShift 4.20.1 with
- 3x control plane, each with 8 cores and 16 GB of RAM
- 3x worker nodes, each with 8 cores and 16 GB of RAM

At one point the rendezvous host stuck with "no space left on device"

With 32 GB of RAM for control plane nodes, the installation is successful.

Attached is the screenshot of the rendezvous host.
