Release 4.7.14-1

Release 4.8.0-1

• Milestones link
• Release date: TBD
• Pre-prod deployment date: TBD
• Prod deployment date: TBD
• v4.8.0-0.rc5 has been released on top of v4.7.14-1 - deployed to pre-prod on 24 Nov

Public Release

• Latest version available on public repo: v4.7.14-1, v5.7.14-1 (any issue in our prod deployment?)

Release 4.7.14-1

• Everything looks ok on the prod deployment, except for verification (which is deactivated, so has no impact).
• These issues with verification will need to be evaluated, but can be done it parallel with future releases (see #223 and #224)

Release 4.8.0-1

• Vlado will need to do some tests before we release, but we have the consensus to move on.
• It would be very desirable to release this before Christmas (in the space of 2 weeks), so that it can be used and evaluated during that period.
• We will merge the branch to main (squashed) before releasing.

 

 

3 CTA dev topics

Rotate files hourly

• Some instanced generate a massive amount of logs (ex. 500GB over 12 hours). We need a way to control this.
• Ops issue discussion on #ops-921

REPACKING tape state and queue cleanup

• Testing of release candidate version v4.8.0-0.rc5. Feedback will go on: #83

Testing encryption key ID changes in tape server code

• Do test release? #139

Update mhvtl in the CI gitlab and CTA repo

• Discuss how the update will be done: #177

"Needs discussion" topics

• Issues link

"Dev issue needed" topics

• Ops issues link

Too many issued CTA and EOS-CTA logs

• Dev ticket #225 was created to evaluated what we can do on the CTA side to control the frequency of these logs.

Testing encryption key ID changes in tape server code

• Manual tests will be done after the 4.8.0 is deployed. These tests will require a while to complete.

Update mhvtl in the CI gitlab and CTA repo

• Jorge and Julien will create a new CI runner to test the usage of the new MHVTL package. A dev ticket will be created for this.

Fix on EOS 4.8.94

• The reason for the bug has been found on [#205](https://gitlab.cern.ch/cta/CTA/-/issues/205). We should work with the EOS team to see if the fix can be released quickly.
