Hi Wei, Thanks a lot for your message. It s really good to hear no 3rd redirector is needed. I will give a try and see how it works. Thanks again, Yujun ________________________________ From: Yang, Wei <[log in to unmask]> Sent: Tuesday, March 27, 2018 10:58:39 PM To: Yujun Wu; xrootd-l Subject: Re: Help with a xrootd redirector configuration question Hi, This is possible with xrootd redirect (http://www.xrootd.org/doc/dev48/xrd_config.htm#_Toc496911346). In this case, you donąt need a redirector for server A and B. Users always access A, and will be (transparently) referred to B if A doesnąt have the file. A and B can, by themselves be redirectors of xrootd clusters. regards, -- Wei Yang | [log in to unmask] | 650-926-3338(O) -----Original Message----- From: <[log in to unmask]> on behalf of Yujun Wu <[log in to unmask]> Date: Tuesday, March 27, 2018 at 6:31 PM To: xrootd-l <[log in to unmask]> Subject: Help with a xrootd redirector configuration question >Hello, > > >Could somebody help me with a configuration question?
