Sure.

Usually you end up with a framework, even if you start without one, so
I think picking one right at the start is a good idea. The top-level
code could be something like:

GetLock();
disk_state = GetDiskState();
db_state = GetDbState();
disk_operation_list = ComputeDiskOperationList(disk_state, db_state);
ApplyDiskOperations(disk_operation_list);
ReleaseLock();

The Get*State() methods would interact with the environment, so I
wouldn't expect much tests for that part. The
ComputeDiskOperationList() function on the other hand would do the
critical work, so I would expect that there would be a set of sample
inputs and expected outputs. This way we'll be able to add support for
newly discovered corner cases while ensuring that all the previous
cases are still working correctly.
