LFC launching at AGLT2

  • Status/news

LFC launch at UC

  • Status/news
  • All done.

LFC launch at IU

  • Status/news
  • Found bug in pilot

BU

  • Had been migrating to PRODDISK. Wanted to complete this before the switch.
    • Question of whether to use lcg-cp. John: use simple "cp", since space token disks are mounted.
    • Require an update to the pilot? Will require development. Try first with lcg-cp.
    • Last time - troubleshooting left off with a submit error, will try again.
  • All ready to switch to LFC.

UTA

  • Ready to get started.
  • Have been busy getting space tokens straight. Trying to use USERDISK today.
  • Later this afternoon will start.

OU

  • No major updates - data migration a few times, working.
  • Plan on next week when Horst return.

LFC-based data management tools (Patrick, Charles)

  • last week
    • Integrity check needs to be modified for GPFS back ends.
    • Deletion tools require BDII - but we've not accepted this as accepted service in US ATLAS, so we'll need to program around it. Charles will be in contact with Stephane.

Pilot progress

  • Can use space tokens with xrootd. Next release, tomorrow. Will use at UTA.
  • More testing jobs sent to IU.

Space reporting

  • Old http interface to LRC also reports space, which the pilot uses.
  • Needs to keep running to report space usage, for the moment; move

URL's in the Catalog

* Discussing issue of full URLs in the catalog. Easier to service. * However, how to avoid truncation when registering files. lcg-rf registers the short version. Paul is using lfc-createg, lfc-addreplica. * Paul will send example - work with Marco to get full URL in the catalog
