Eg:
server A (datacenter 1) and server B (datacenter 2) hold replica (100) for volume 1.
If you upload a file with a key 1,xxxxx to server C (datacenter 3) will trigger the panic on server C.
The server C should either proxy upload file to the correct volume server or should return an HTTP error code and not panic.
