Hi,

  I am trying to understand why my use of xrdalder32 command is failing.

I have a file in xrootd storage -
I can see it from the redirector 

[root@wnode01 ~]# xrd hnode.atlaspitt:1094 locateall /atlas/local/bdouglas/data11_7TeV.00180224.physics_Egamma.merge.NTUP_EGAMMA.f368_m806_p536_tid327358_00/NTUP_EGAMMA.327358._000001.root.1


------------- Location #1
InfoType: kXrdcLocDataServer
CanWrite: true
Location: '192.168.100.101:1094'

Yet I get this result from xrdalder32

[root@wnode01 ~]# /usr/bin/xrdadler32  root://hnode.atlaspitt:1094//atlas/local/bdouglas/data11_7TeV.00180224.physics_Egamma.merge.NTUP_EGAMMA.f368_m806_p536_tid327358_00/NTUP_EGAMMA.327358._000001.root.1
Error_accessing root://hnode.atlaspitt:1094//atlas/local/bdouglas/data11_7TeV.00180224.physics_Egamma.merge.NTUP_EGAMMA.f368_m806_p536_tid327358_00/NTUP_EGAMMA.327358._000001.root.1

I get a similar error when I query the data server with the file :

[root@wnode01 ~]# /usr/bin/xrdadler32  root://wnode01.atlaspitt:1094//atlas/local/bdouglas/data11_7TeV.00180224.physics_Egamma.merge.NTUP_EGAMMA.f368_m806_p536_tid327358_00/NTUP_EGAMMA.327358._000001.root.1
Error_accessing root://wnode01.atlaspitt:1094//atlas/local/bdouglas/data11_7TeV.00180224.physics_Egamma.merge.NTUP_EGAMMA.f368_m806_p536_tid327358_00/NTUP_EGAMMA.327358._000001.root.1

Yet when I query the actual file on disk:   the xrdalder32 succeeds.

[root@wnode01 ~]# /usr/bin/xrdadler32  /local/xrootd/a/atlas/local/bdouglas/data11_7TeV.00180224.physics_Egamma.merge.NTUP_EGAMMA.f368_m806_p536_tid327358_00/NTUP_EGAMMA.327358._000001.root.1

Am I doing something wrong or did I find an undocumented feature.

Thanks,

Doug Benjamin
