Hello, XRootD experts.

I have a question about "xrootd.redirect" feature of xrootd.

I'm trying to connect the xrootd server (not redirector) to a dCache's xrootd door as a backend.

There are many examples, so I'm going to try to follow them, but it doesn't work well.

The settings for the xrootd server I set are as follows.

xrd.port 1097

all.export /

all.role server

xrootd.redirect cms-t2-se01.sdfarm.kr:1094 all /

ofs.forward cms-t2-se01.sdfarm.kr:1094 all

cms.dfs lookup central

cms.trace all

Symptoms that followed these settings are as follows:

1. Directory navigation works well. The directory structure of dCache xrootd door on the 1094 port is displayed well.

2. Meta commands such as "stat" is work well for files.

3. Attempting to open or copy a file (such as root command or xrdcp) results in an Internal Error.

How can I use it as a complete redirect?
