Hi Brian,

As I replied  in GGUS ticket
(https://gus.fzk.de/ws/ticket_info.php?ticket=37669) we looked into
the problem and found that the files you are trying to copy are lost.
It did exist in the pnfs file system  however had zero length and no
information what pool does host it. As this is useless we have had to
delete it completely and I'm afraid there is no way to restore it
since we had no replica manager running on dcache01 at the time the
file was created  (12/06/2008) and there is no copy of the file in our
system.
As you know dcache01 was in unstable condition in a past few months
having been upgraded, reconfigured, restarted many times. During this
time some information (apparently without replica) might be lost.
Please accept our apology.
Now the system has replica manager running and is in more stable
condition. We hope this will not happen again.

As for srm2.2 use this endpoint:
