ATLAS tests
March 2020: we decided to start small scale testing in production
- ATLAS infrastructure: rucio & fts-atlas
- 3 sites: Manchester, Lancaster, Prague
- All DPM but connected to the people doing the work
- Only pull mode
- Functional tests enabled for both protocols
Several problems appeared tracked here ADCINFR-166
Mid May: we kind of ready to restart but too many things still don't click
HTTP-TPC
- DPM 1.14: almost ready but release date not clear only Prague has it installed
- Manchester, Lancaster, Naples and Lapp will follow when new version is released
- Dcache: sites with any version 5.2+
- Previously asked AGLT2, FZK, Pic and Triumf
- AGLT2 already notified others need reiteration
- FTS-atlas upgraded to 3.9.4 done yesterday
- Storm, echo EOS and xrootd will follow
Xrootd-TPC
requires enabling request signing and in the summer TLS will be released. To avoid asking sites to reconfigure to often their production instances we decided to wait for TLS before asking for other sites for now we will test Xrootd-TPC with SLAC and OU with request signing on. xrootd team will try to accelerate TLS code.
Tests for both will go on over the summer (hopefully without further major problems)
CMS Tests
CMS restricted to http mostly dcache and isn't using rucio yet
Outh2.0 testbed
Decided to go ahead with wlcg IAM, doma rucio instance and FTS-devel (being upgraded to 3.10).
Documentation https://wlcg-authz-wg.github.io/wlcg-authz-docs/
Sites are adding WLCG VO to their storages VOMS configuration but for this testbed we also need additional configuration for tokens. DESY, CNAF, Nebraska, Manchester and prague can participate with testbeds.
There was a presentation last week
SRM/tape
Discussion onthe mailing list about TPC with SRM and non gridftp protocols.
SRM can use also other protocols ie a command like this is expected to work
gfal-copy -vvvv
'srm://storm-fe.cr.cnaf.infn.it:8444/srm/managerv2?SFN=/atlas/atlasscratchdisk/SAM/1M'
https://golias100.farm.particle.cz/dpm/farm.particle.cz/home/atlas/x
it works with dcache and storm needs to be configured.
Dcache is developing an alternative to SRM based on the REST API andit behaves differently. Another problem with SRM is that it still needs x509 while we are working on tokens.
CTA already does BringOnline triggered by FTS without SRM. Other people showed interest in this solution.
Discussion stopped at "inwhat forum we should discuss this". Current proposal is to add phase 5 to TPC.
