Support Update

  • Colorado (BrianL): OSG-issued IGTF certs won't work because their IT won't issue a PTR pointing to the OSG domain
  • Brown (Derek): Supporting XRootD configuration. Using standalone config, but also copied from other server that was working before. Old LCMaps configuration.
  • Caltech (Derek)/LIGO (Carl): Debugging accounting information not showing up in the GRACC or in Gratia logs. (These are two separate tickets for the same issue; BrianL will merge them)
  • UERJ (Carl): Provided support for tuning GridFTP configuration
  • Hosted CEs (Carl): Hosted CEs failed to quarantine history files because the Gratia probes run as the 'condor' user and do not have write permission to the quarantine directory. This results in zero-length jobs not being reported to GRACC

OSG DevOps

New: - Request to inject entire HTCondor job classad into GRACC records. Will require gratia-probe-condor changes. - StashCP Go client is now being used and distributed with every OSPool Glidein! Being used in the stash:/// transfer plugin and starting to be used by Mats on his singularity image distribution.

Ongoing: - Elasticsearch will need to be updated, scheduled for last week in August. Planning ongoing. - Design document is done and is being distributed for xrootd monitoring collector NG (next gen). Shoveler is working and lightly tested. Collector is 90% done. Design document is still not reviewed, but moving foward anyways. - Discussions of xrootd-multiuser support for checksumming on-the-fly. After a discussion, the checksum-on-the-fly funcationality will be ported to xrootd-multiuser. Copied largely from xrootd-hdfs. This does mean that out-of-order writes will not be supported.

Back burner: - (Stalled, but need to get back to it) XRootD accounting information (from Frank): - May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer. - Table of working set, read, and re-read for monthly, quarterly, and year. - XRootD TCP plugin is ready for packaging. Derek will follow up with software team on who to hand that off to. -
