News:
- Tentative next procurement meeting next Friday (2/27). An email to Tier-2 managers has been sent. We will try to avoid clashing with the US ATLAS management meeting like last time.
- dCache version 11.2 only included fireflies for xroot transfers. dCache version 11.2.1 is supposed to have fireflies for all protocols. It also includes tape metadata capability.
- If your site is testing it and has results, please share news during the rount table (and enter in the minutes)
- Short mini-capacity challenge happening today between PRG-NET2 [notes]
- Keep the capacity and services spreadsheets updated. Keep CRIC and OSG topology updated when servers are added or retired.
Certificate issues:
- The transfer problems between SWT2 and IFIC/TECHNION was due to X.509 certificates with the full chain being used.
- StoRM systems only accept leaf certificates, which we agreed is not the correct procedure.
- WLCG and/or ATLAS do not have, in practice, any way to enforce sites to accept full certificates.
- A workaround has been used at SWT2 (see more details in Zach's minutes below) by using a leaf certificate in some servers. Apparently other sites do the same.
- This is not the correct procedure, and it will cause problems in the future with systems that only accept full-chain certificates (as it was the case for Google, for instance)
- Horst will open a ticket with OSG to understand what kind of certificate is being used.
