Site reports


Things are running fine -- as far as we can tell.

ATLAS have stopped migrating data on a large scale; SRM is stable again.

Controlling staging concurrency

Ticket #8545

set the max number of "rc set max restore" no actual stage activity was

HTTP upload/download tests

Ticket #8543

CURL HTTP. Sleep downloads are successful. Uploads may fail.

Tigran has suspicion where the problem lies, but need to discover whether fixing this would introduce new problems.

We can try to reproduce the problem here at DESY.

Logging behaviour

Ticket #??

Strange logging configure

RPM did not replace existing logback.xml, but replaced logback.xml.rpmnew.

Look into what we can do to improve this for future releases.

File deletion

Is a file deletion recorded from all doors? For 2.10, all except NFS.

Please open ticket for NFS reporting file deletion.


Tape movement -- working fine.

Net bug in dCache v2.11. We are running test system -- tests file -- ATLAS deletes file sometimes, OpenSSL Ubuntu and SL-5 -- SRM commands die.

Please send commands that demonstrate the problem.

Problem is not affecting dCache v2.10.
