The have a list of lost files and more infos here List of affected phys-v2-lumi2 decays What data (what decays) are affected?

While running this is done in sequence, so the file is only staged at the moment the algorithm wants to use it. This is of course very time consuming. But there is a possibility to pre-stage the files manually and in parallel. text/html 2009-01-27T08:50:36+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.physik.uzh.ch/lhcb/castor:storecastor?rev=1233046236&do=diff Storing Data on Castor Introduction Castor is a storage manager system used to store physics production files and user files <http://castor.web.cern.ch>. It can be used to store large files that are too large for your lxplus account. The access to the files is however a bit different than on lxplus. text/html 2014-02-05T14:26:22+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.physik.uzh.ch/lhcb/castor:transferzh?rev=1391610382&do=diff Copying Files from CASTOR to Zuerich directly Note: Transfer Instructions for Grid How to In order to copy files directly from CASTOR to a machine in Zurich, login to the machine grid-ui. There do lhcb-proxy-init which will prepare for file-transport. Then do (e.g.): lcg-cp -v 'srm://srm-lhcb.cern.ch:8443/srm/managerv2?SFN=/castor/cern.ch/user/myInitial/myUsername/myFile' file://home/hep/myUsername/myFile
