Unable to perform queries on DAS #38

Closed tommasodiotalevi closed 2 years ago

tommasodiotalevi commented 2 years ago

Dear DAS experts, I am currently unable to perform queries on the web interface of CMS DAS. For instance, I am trying to perform this simple query: dataset=/DYJetsToLL_M-50_TuneCP5_13TeV-amcatnloFXFX-pythia8/*20UL*/NANOAODSIM

receiving only 1 result with the query I just inputted, instead of the list of related datasets.

Best, Tommaso

@Tommaso93 I'm not sure I understand the question. If you specify a concrete dataset which related dataset you're looking for? If you want to find dataset which satisfies a certain pattern you should use a wild-card, e.g. to find all datasets which starts with ZMM you will do the following query dataset=/ZMM*/*/*.

Yeah, sorry the * was included in the 20UL string, but formatted as italic in markdown.

dataset=/DYJetsToLL_M-50_TuneCP5_13TeV-amcatnloFXFX-pythia8/*20UL*/NANOAODSIM this is the correct example. If I put this query, I only receive one result (the query itself). I see that another issue has been created #39 which might be related.

Please check now, everything is working, it was an issue with das maps which pointed to k8s cluster which was deleted due to CERN IT incident. I'm closing the ticket, please re-open if you'll find issue again.
