Hi,
In a xrootd dataserver that is connected to a gridftp server on another
machine through the xrootd-dsi library from OSG, I am seeing errors locating
a file that was written to disk.
111219 12:22:34 12371 ofs_stat: xrootd.12469:24@atlas8 Unable to locate
/atlas/user/willocq/data11_7TeV/user.willocq.data11_7TeV.periodAllYear.physics_Muons.PhysCont.AOD.pro10_v01.MuonESDAnalysis-00-00-71.111203082438/user.willocq.001062.EXT0._05657.ntuple.root__DQ2-1324317868;
No such file or directory
Yet the file exists -

Goodbye.
This file is also visable from uberftp -

This behaviour makes it difficult to use this type of configuration in the
ATLAS data distribution system.
Thanks,
Doug Benjamin
