        EOSCTA Post-Migration Issues 10m

        TOTEM

        • #334 Migrate TOTEM files from EOS to CTA. Michael is following up with TOTEM.
        • RQF1790785 Archival EOS files in CTA

        NA62

        • Protect DAQ user from deleting files written by DAQ. #295 Fix ACLs for NA62 on CTA PUBLIC, #297 Testing of p and !d eos permissions, #304 Testing of !d ACL.
        • #291 T2 transfers are working because the firewall was opened, but this is a temporary situation. Any WLCG site wishing to access CTA must be on LHCONE.
        • NA62 have asked for a one-week extension of the firewall opening: "We are starting to write to EOS (and asynchronously move the files to CTA). However, would it be possible to give us a one-week extension just so that the existing production rounds finish as they are (and we don't have their output split between EOS and CTA)?"

        ATLAS/ALICE

        • Repack of r_public_user has finished extracting atlas_user and alice_user files to separate tapes. These can now be imported into the respective instances.

        LHCb

        • DAQ hardware delayed, expected in the summer, september at the latest.
        • #306 DAQ integration and testing, including FTS Archive Monitoring
        • LHCb reprocessing campaign (begins in May)
      • 14:10 → 14:20
        CTA PUBLIC Migration from CASTOR 10m

        n_TOF

        • #143 nTOF tests on EOSCTAPUBLIC PPS , #161 Spinners space on EOSCTA PPS
        • w/c 3 May: Start testing with n_TOF (archival through spinner space using Steve's modification to EOS)

        CLIC/ILC

        • #310 CLIC/ILC tests on EOSCTAPUBLIC PPS
        • Migration 1st week in June (provisional). Review w/c 10 May.

        COMPASS

        • #69 COMPASS tests on EOSCTAPUBLIC PPS
        • COMPASS snaphot imported to eosctapps
        • Testing status update
        • Repack of COMPASS tapes complete, some files still in /user part of namespace

        AMS

        • #82 AMS tests on EOSCTAPUBLIC PPS
        • Baosang will proceed with integration work on his side.
        • AMS tapes have been repacked.
        • Plan is to migrate AMS to CTA by end of May.

        NA61/SHINE

        • NA61/SHINE: setting up their DAQ system + storage. No schedule for testing yet.
        • Decouple online and offline workflows, migrate offline to CTA.
        • Start offline testing.

        Backup

        • #307 Migrate CASTOR Backup use cases to CTA
        • /afsmigration #282.

        Other Use Cases

        • HARP - #344 - ready to migrate. Preservation VO. Which instance (with or without spinners)?
        • ArDM - #342 - needs 1 tape repacked
        • NA48 - #341 - needs 3 tapes repacked
        • r_public_misc: covers most of the rest of the small experiment use cases. Needs repacking to separate from r_public_user.
        • LEP tapepools: postponed until more files have been repacked.
      • 14:20 → 14:30
