So if you look at the files in oss.space, you can grab the attribute like this: # cd /data/pool1/public/00 # getfattr -d 09172E58E91400000000c0aae37c000300000C6% # file: 09172E58E91400000000c0aae37c000300000C6% user.XrdFrm.Pfn="/data/xrootd/atlas/uct3/data/users/blahblahblah/foo/bar/baz.root" From there you should be able to whip up a script to reconstruct the namespace. Hope that helps. --Lincoln ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
