Follow-up Comment #3, bug #87960 (project xrootd): More information to help... Dual nic still and issue. On the dual niced machine (atlas8 and atlas21). I have [root@atlas8 ~]# cat /proc/sys/kernel/hostname atlas8.hep.anl.gov [root@atlas8 ~]# hostname atlas8.hep.anl.gov [root@atlas8 ~]# uname -a Linux atlas8.hep.anl.gov 2.6.18-238.19.1.el5 #1 SMP Fri Jul 15 00:48:58 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux Using the xrd command - queryspace /atlas I get - [root@ascint3 ~]# xrd atlas21.hep.anl.gov queryspace /atlas sec_Client: protocol request for host atlas21.hep.anl.gov token='&P=sss,0.216000:/var/spool/xrootd/.xrd/sss.keytab.grp' sec_PM: Loading sss protocol object from libXrdSecsss.so sec_PM: Using sss protocol, args='0.216000:/var/spool/xrootd/.xrd/sss.keytab.grp' sec_sss: Client keytab='/var/spool/xrootd/.xrd/sss.keytab.grp' sec_sss: Ret 151 bytes of credentials; k=1 sec_Client: protocol request for host 127.0.0.1 token='&P=sss,0.13:&P=unix' sec_PM: Using sss protocol, args='0.13:' sec_sss: Ret 151 bytes of credentials; k=1 Disk space approximations (MB): Total : 578993 Free : 549384 Used : 29608 Largest chunk : 549384 Here is what xrootdfs reports when mounted: [root@ascint3 ~]# mount -t fuse -a sec_Client: protocol request for host atlas21.hep.anl.gov token='&P=sss,0.216000:/var/spool/xrootd/.xrd/sss.keytab.grp' sec_PM: Loading sss protocol object from libXrdSecsss.so sec_sss: Client keytab='/var/spool/xrootd/.xrd/sss.keytab.grp' sec_PM: Using sss protocol, args='0.216000:/var/spool/xrootd/.xrd/sss.keytab.grp' sec_sss: Ret 151 bytes of credentials; k=1 sec_sss: Ret 151 bytes of credentials; k=1 [root@ascint3 ~]# df -h /atlas21/atlas Filesystem Size Used Avail Use% Mounted on xrootdfs 566G 29G 537G 6% /atlas21/atlas Now if I set the host name of the stand alone data server to atlas21 and restart xrootd on the machine.

I can use the xrd queryspace command to see the same problem. 2) the problem is repeatable 3) I am not sure where xrootd is getting the weird values to present. 4) This is fairly serious _______________________________________________________ Reply to this item at: <http://savannah.cern.ch/bugs/?87960> _______________________________________________ Message sent via/by LCG Savannah http://savannah.cern.ch/
