I believe that this is handled in a rather abrupt way at the server. It will crash and if you have replication the partition leader will move. However you must manually solve the disk space issue before restarting the failed broker since replication will immediately crash it again. (The same thing also applies to a broken disk) I think that partition-reassignment requires a healthy broker but I might be wrong on this. /svante
