Discussion¶
Support Update¶
Edgar: - Georgia Tech StashCache using very old version of the packages; the error is about not being able to get an Authfile from topology. - Clas12 is registered as a project but not a VO, which was causing issues because they are sending batch records tagged with a "Clas12" VO. Since they are part of JLab, they should be under the JLab umbrella but they are using their own top-level VOMS attribute. Clas12 will be registered as a VO under the JLab VO in topology (similar to how DUNE is registered).
Diego: - Helped Riccardo di Maria set up an XRootD dev environment. Riccardo was compiling XRootD himself, which resulted in a different version number for XRootD and this led to dependency resolution issues when installing the plugins. - Worked with JINR sysadmin to test HTTP transfers between UCSD and JINR.
