Hi,

The name indicates that they’re the relaylogs used during GR recovery phase. Ideally relay logs should be auto clearedup once they’re no longer needed! Was this node created by a physical copy from another node and hence they’re here? If so, yes good to clean. Also date shows that they’re old and shouldn’t be in use currently. Plus the size is also tiny!

I am not sure what you meant “parameter is on. How can ı this station?”

“Can we delete regularly delete?” > No, they should be deleted by the system itself
