Hi all,
We currently have problems with xrdcp for our local resources.
We have a XRootD server and redictor on a ceph node to provide local datasets of our users to the (external) worker nodes of our T3 via XRootD.
Setup:
Ceph configs: data server, redirector
On the worker node, a caching proxy and a redirector are running. Configs: proxy, redirector
The client is configured to use the redirector. Config: client-plugin-proxy.conf
What we observe
xrdcp fails for current versions (tested with: 5.5.1)
What we see is that the final url is build up correctly (final_url=root://f03-001-110-e.gridka.de:1094//root://ceph-node-j.etp.kit.edu:1094//mschnepf/data_mnist-tar.gz), but the transfer somewhat fails with the error:
[0B/0B][100%][==================================================][0B/s]
Run: [ERROR] Operation is not implemented: (source)
Full log: transfer_5-5-1.log
With older versions of xrootd, however, our setup works fine, see transfer_5-3-1.log.
I tracked it down to the client(config) or the redirector.
If I do not use the redirector but ask the server directly, it works with a current xrootd version (5.5.4). Log: transfer_5-5-4-without.log
What I also observed was that changing the major version in "lib =libXrdClProxyPlugin-.so" in the client plugin conf
does not have any influence. When changing it to V=1000, the redirect still works (and it still fails :D).
Just wanted to make sure that this behaviour is intended.
Maybe also our configs may aren't compatible with newer versions. If so, thanks for any help in advance to fix it! :)
Thanks and cheers
