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
