OSG Software Team

  • 15 tickets will be opened with edg-mkgridmap/GUMS sites to transition to LCMAPS VOMS authentication
    • There are already instructions for edg-mkgridmap to transition.
      The timeline we'd like to see is that edg-mkgridmap sites transition by the end of March.
    • GUMS sites are trickier:
      • If they attach their GUMS config, MAKE SURE THEIR DB USERNAME/PASS ARE REDACTED
      • Find out what GUMS clients they may have: CE, gridftp, xrootd, dcache, bestman. The first three all support LCMAPS VOMS auth, dcache and bestman2 do not. They cannot turn off their GUMS until they transition off of dcache/bestman2.
      • Let Carl know of any attached GUMS configs and the output of `rpm -q osg-gums-config`.
  • GCT: Frank Scheiner registered Gitbook/ReadTheDocs orgs but hasn't worked on the documentation other than that. Let's get started on making the transition from Globus to GCF/GCT. I can help setup GitHub docs.
  • OSG 3.4.7
    • HDFS tested at Nebraska, looks good over the weekend
    • Can we sneak HTCondor into this release?
  • GOC tickets should be closed in favor of JIRA tickets if the user agrees to it (GOC vs JIRA):
  • Doc Focus 2 is scheduled for 1pm CST on Feb 1


Edgar would like notes on how to determine what auth clients are using for help with the LCMAPS VOMS transition

Support Update

  • (Carl) - errors are showing because of empty data from GRACC; trying to replicate
