Indeed, something looks suspicious: [bbockelm@brian-test ~]$ xrdfs red-gridftp3.unl.edu 'ls /store/temp/foo' [ERROR] Server responded with an error: [3011] Unable to locate /store/temp/foo; no such file or directory [bbockelm@brian-test ~]$ xrdfs red-gridftp3.unl.edu 'stat /store/temp' Path: /store/temp Id: 0 Size: 4096 Flags: 59 (XBitSet|IsDir|Offline|IsReadable|IsWritable) This used to work - perhaps we had a regression somewhere along the line?
