Adding nodes to swift

If I add a new node of storage,it need to rebalance the ring and restart the swift thread.I want to know that whether this process can make the upload or download file from swift error?

If adding nodes can make the upload or download error,how can I solve the issue?Or how can I add the nodes without restarting swift thread(dynamic adding nodes )/

You don't need to restart the servers for them to pick up the new ring, they'll check for changes and reload them every so often automatically:

On a related note swift wsgi servers handle SIGHUP to signal a soft restart. The parent process will restart and spawn new workers to accept new connections while the rest of the workers will finish servicing existing connections before terminating.
