Getting LHCb into Production

• Several blockers on XRoot + EOS side, fixes are in the pipeline. Julien will follow up at tomorrow's x-section meeting.
• HTTP+TPC: we should be able to test transfers with CNAF, in both directions, using delegated X.509 credentials.
• In parallel, Julien will continue with configuring and testing token authorisation. This is not a blocker for the LHCb migration.
• LHCb DAQ tests to EOS have started but they are experiencing some issues. They are throttling at 1.5 GB/s per machine, whereas they should be seeing throughput of 10 GB/s. Maria is debugging this with Chris and the networking team. It makes sense for us to wait until these are resolved before we run any tests on our side.

Getting PUBLIC into Production

• (From IT/SME meeting) AMS are keen to resume testing as they are blocked by the 1m file limit. It seems that the filename structure they use is hard-coded in many of their scripts and would take some time to fix. Those are really two separate issues (the CTA migration and the problems created by having too many files in a directory). This should be followed up in x-section meeting.
• CAST errors seem to be caused by retries on their side of files which have not yet made it to tape. As the files have the same filename, the retry is failing. Julien is following up, see INC2684046.
• Repack of r_public_user: 150 tapes to go.

CTA Status Update

• Cedric will deploy 3.2-1, then 4.0-1.
• Reclaiming a tape will empty the recycle bin and remove the IS_FROM_CASTOR flag so that it can be added to a supply pool. Files cannot be recovered from the tape after it has been reclaimed.
• Next, Cedric will investigate issue #930 CTA Frontend crashes after removal of repack request with 15000 files
