GridPP Technical Meeting - Rucio / DIRAC integration

Friday 11 Feb 2022, 11:00 → 12:00 Europe/London

Virtual Only

Alastair Dewhurst (Science and Technology Facilities Council STFC (GB)), Andrew McNab (University of Manchester), David Colling (Imperial College (GB))

Weekly meeting slot for technical topics. We will try and focus on one topic per meeting.  We will announce at the Tuesday Ops meeting if this meeting is going ahead and if so the topic to be discussed.

There was a brief verbal update for ECDF around their activities with the following actions:
- Alastair to start a conversation around monitoring between ECDF and RAL.
- RAL to contact Wenlong when Anatares is ready for Dune to use.

Tim Noble presented an update for RAL (see attached slides).

 

Janusz gave a verbal update:

Rucio side:

- adapted Belle-II server-side Dirac - Rucio interface to serve multiple VOs. The code in the the PR (#5125), accepted by a Belle II rep. 
- the changes are implemented in the IC server, configured to work with Dirac (it used Dirac scope extraction algorithm)

Dirac side:

- the RucioFileCatalog client was adapted to serve multi-VO.
- 2 agents (“crons”) we also modified for multi-VO
  — one of them syncs Dirac SEs and users from Dirac to Rucio accounts/RSEs
  — the second one enables/disables them based on their Dirac status

Everything has been put together and tested at IC.

A PR on Dirac also exists, waiting fot Rucio PR to go first.
