Migration of CASTOR home directories Room: 600/R-001 * [OTG0064878](https://cern.service-now.com/service-portal?id=outage&n=OTG0064878) Closure of CASTOR home directories * [#390](https://gitlab.cern.ch/cta/operations/-/issues/390) Migration of CASTOR user accounts to CTA * Experiment data has been separated from user data as far as possible. New fileclasses to distinguish between primary accounts, secondary accounts and service accounts. `do_not_migrate` fileclass for data which should probably be deleted. ### Summary * 971 CASTOR users. Around 1/3 of them have <100 files. * total count of files: 61,765,238, total size: 4.9 PB * 7 users with >100 TB. 246 users with >1 TB. * Only around 20 users who wrote data to CASTOR in the last year. These seem to be mainly experiment analysis or MC use cases. ### Strategy 1. Clean up/delete unneeded files where possible 2. Migrate users with <1 TB to CERNBox. Currently if we total up files for all users with <1 TB it comes to 76 TB. 3. Users with >1TB, 2 options: - let them negotiate a higher limit - leave their data on tape and migrate it to CTA (last resort) ### To Do * Need a policy for users who have left CERN and left files behind in CASTOR.

CASTOR Backup Room: 600/R-001 * [#307](https://gitlab.cern.ch/cta/operations/-/issues/307) Migrate CASTOR Backup use cases to CTA ### Use cases * EOS archive tool **Migrated to CTA** * Messaging * Oracle * EOS * Hadoop * AFS ([#282](https://gitlab.cern.ch/cta/operations/-/issues/282)) * Zvault (Microelectronics and NFS Filer)

Cold Data Room: 600/R-001 * NA48 - [#341](https://gitlab.cern.ch/cta/operations/-/issues/341) - repack underway * `r_public_misc`: covers most of the rest of the small experiment use cases (single copy). Repacking will separate from `r_public_user`. * `r_public_user_[1,2]` is other small experiment data (not user data despite the name of the tapepool), dual copy. Merged with `r_lep_data_[1,2]`.
