ALICE Post-migration Room: 600/R-001 * Namespace reconciliation: Michael provided Costin with list of 2m files in Alien which are not in CTA. * ALICE probe status ([#105](https://gitlab.cern.ch/cta/operations/-/issues/105) and [#666](https://gitlab.cern.ch/cta/CTA/-/issues/666)). * Implicit prepare status (implemented, needs a CTA release). * Garbage collector status ([#905](https://gitlab.cern.ch/cta/CTA/-/issues/905)), needs feedback from Andreas. GC will be needed mid-November.

Getting CMS into Production Room: 600/R-001 * See [Putting EOSCTACMS into Production: TO DO List](https://codimd.web.cern.ch/0ahsdsCuQaGQ_nPGrKZWTg) * See [Notes from meeting with CMS 02/10/2020](https://docs.google.com/document/d/1MBjkDBZz0_RafBswmR4NGLhrq_KiIwNRJ-QHWhiJf28/edit) * CASTOR namespace has been cleaned up prior to migration. **TO DO** * Test EOS Backup (Elvin's daemon and user backup tools on EOS CMS) ([#113](https://gitlab.cern.ch/cta/operations/-/issues/113)) * Repack tapes in cms_user (following list in [CASTOR /user directories split across multiple file classes](https://codimd.web.cern.ch/mn80xbRjSqaewdpXyQPyjQ?view#)). Not a blocker if this is not finished prior to migration, we could remove tapes needing to be repacked from `r_cms_user` and migrate them after repack. * Test archive monitoring (either FTS or homebrew using `xrdfs query prepare`) * OTGs: CASTOR and CTA **Schedule** * **28 Oct 2020:** CTA recall test (not a scale test, recall some datasets from various eras of the experiment) * **9 Nov 2020:** End-to-end functional "replay" tests at T0 (pre-MWGR tests, with CASTOR) * **18 Nov 2020:** MWGR#4 wiith CASTOR * **w/c 23 Nov 2020** Put CASTOR CMS into recall-only mode * **30 Nov 2020:** Migrate to CTA * **07 Dec 2020:** CMS in production * **End Dec 2020? :** CMS retires PhEDEx

Getting LHCb into Production Room: 600/R-001 * See [Putting EOSCTALHCB into Production](https://codimd.web.cern.ch/Q2d7McJXRkCMU6uI2nO6Ig#) (CodiMD) * Successful 200TB test with 10 tape drives and one buffer server for 2.5GB/s of constant archival throughput. * Successful transfer using Dirac to move a file from EOS to Gridka via HTTP ([FTS monitoring](https://fts3-pilot.cern.ch:8449/fts3/ftsmon/#/job/3f02eda2-146e-11eb-9466-fa163ea8183c))! **TO DO/Schedule** * w/c 2 Nov : 200 TB recall test * Test HTTP TPC with CTA (FTS multi-hop with one "hop" as QoS change, one hop as the transfer) * DAQ test should be possible in November (tentatively 9 Nov 2020)

Getting PUBLIC into Production Room: 600/R-001 * Migration of SMEs from CASTOR to CTA, see [Putting EOSCTAPUBLIC into Production](https://codimd.web.cern.ch/9KYwU8VsQ3a8_0CgZnuvkA#) **NA62** * NA62 repack is proceeding * NA62 offline integration: Vova has created the VM with AFS+EOS to allow the tests to proceed * NA62 has been migrated onto EOSCTA PPS ([#72](https://gitlab.cern.ch/cta/operations/-/issues/72)) * **w/c 9 Nov :** NA62 recall tests (30 TB) on EOSCTA PPS **COMPASS** * Metadata check checksum bulk query: they will do it the slow way for now * **Wed 4 Nov 2020 :** DAQ tests on CTA. * EOSCTA instance for these tests, see [#69](https://gitlab.cern.ch/cta/operations/-/issues/69) COMPASS tests on EOSCTAPUBLIC PPS **AMS** * Meeting with AMS took place 29/09/2020 * They have an endpoint * Need them to test it **NA61/SHINE** * Trying to schedule a meeting **Identifying hot/cold data** * Vova is looking at CASTOR logfiles to try and build a profile of when data was last accessed and by whom.

Repack Room: 600/R-001 **Repack of public_user** * Many experiments have data under their part of the namespace in the `public_user` fileclass. This prevents us from migrating small experiments one-by-one. * `public_user` needs to be split into "real" user files, small/medium experiment files and legacy experment data * Need to create new tapepools with archive routes etc. * Around 1,500 tapes need to be repacked **CTA Repack: status update** 1. Deploy and test: (a) Injection of recovered files when repacking broken tapes, (b) Change mount policy on-the-fly. 2. Tape Server: Add configuration options to give greater control over the highly-distributed maintainence process. 3. Remove "superseded" files in favour of the recycle bin. 4. Investigate if we can run a separate repack instance sharing the same catalogue.
