Maybe the fact that the hosts are on CentOS 8, while the Engine (storage) is on CentOS 7 is relevant. Also the occurrence of this issue seems not to be 100% deterministic, I guess because it is timing related. The error is reproducible locally by running OST, and just keep the environment alive after basic-suite-master succeeded. After some time, the storage will become inaccessible.
