Hi all,

Yes I see both cache and persistent storage data servers

On my client machine, which has the following mount points
# xrootd mounts
#persistent re-director
/tonytest1/coepp -fstype=fuse,rw,rdr=root\://tonytest1.tev.unimelb.edu.au\:1094//coepp,uid=497,sss=/etc/xrootd/coeppkeyfile :xrootdfs.sh
#cache re-director
/tonytest7/coepp -fstype=fuse,rw,rdr=root\://tonytest7.tev.unimelb.edu.au\:1094//coepp,uid=497,sss=/etc/xrootd/coeppkeyfile :xrootdfs.sh
#site level re-director
/tonytest8/coepp -fstype=fuse,r,rdr=root\://tonytest8.tev.unimelb.edu.au\:1094//coepp,uid=497,sss=/etc/xrootd/coeppkeyfile :xrootdfs.sh
I attempt the above command but it doesn't give me a list of data servers
[orso@tonytest4 ~]$ getfattr --only-value -n xrootdfs.fs.dataserverlist /tonytest8
/tonytest8: xrootdfs.fs.dataserverlist: Operation not supported
