New public repos for CTA Alma9 releases

Releases
1

Dear CTA community,

We are happy to announce that we have created 2 new public directories for our Alma 9 CTA releases:

  • https://cta-public-repo.web.cern.ch/stable/
    • Stable CTA releases for Alma 9.
    • These are the recommended versions for other sites to install.
    • Not all CTA versions will be put here. Only the versions that we are confident that work without any major issues, or that are critical for upgrading a CTA deployment.
  • https://cta-public-repo.web.cern.ch/testing/
    • Testing CTA releases for Alma 9.
    • All “CERN internal” CTA releases for Alma 9 will be put here, even if they are not guaranteed to be stable.
    • Can be used by external sited to test and experiment with new CTA features.

For the moment, only the testing repository contains the Alma9 CTA RPMs. We will update the stable repository after we conclude successfully our transition to Alma 9 at CERN.

Hi Joao,

Many thanks for this. We have created mirrors of all the CTA 5 repos for EL9 in our mirror server.

It is possible to give us a rough time scale of when you are plannning to conclude the transition to Alma 9 at CERN?

Hi George,

The hard deadline to migrate to Alma 9 is the CERN CentOS 7 end-of-life (30 June 2024). Our migration plan is tied to the delivery of new servers. All being well we will migrate during May.

Hi Michael,

Thanks for your reply. OK, so you will then populate Index of /stable/cta-5/el9/cta/x86_64 at some point in June. This makes sense given your standard practise to tag as a public release the CTA version that you have by running in production at CERN for about a month. I am afraid, it would be too late for us to start our migration work in June

Would it be please possible to put the 5.10.8-1 rpms in the Index of /testing/cta-5/el9/cta/x86_64?

This is the latest stable version for EL7 and the one we will upgrade to ar RAL in a couple of weeks. It would allow us to start testing the EL9 migration sooner rather than later.

Hi George,

There is no upgrade path for 5.10.8 to Alma 9. There were several issues in the code and dependencies that had to be fixed. So we recommend you upgrade to 5.10.10 before doing the OS upgrade.

We will put the 5.10.10 version into the public repo shortly.

Hello George,

We have made the 5.10.9.1-1 and 5.10.10.1-1 versions of CTA public here (for CentOS-7):
https://cta-public-repo.web.cern.ch/cta-5/el-7/cta-testing/x86_64/

Please keep in mind that we haven’t started deploying 5.10.10.1-1 yet. Therefore, these might have some undetected issues.

Anyway, as Michael mentioned, the version that we plan to use for the migration from CentOS-7 to Alma-9 is the 5.10.10.x. We recommend other sites to do the same.

Best regards,
Joao
