Follow-up Comment #1, bug #86870 (project xrootd): Hi Wei, I see in the system log when I started up xrootdfs but I did not see when the xrootdfs mount processes lost synch with the xrootd file servers. I am seeing these messages - Sep 18 07:45:01 titan XrootdFS[1314]: INFO: use the following 16 data servers : Sep 18 07:45:01 titan XrootdFS[1314]: titan13:1094 Sep 18 07:45:01 titan XrootdFS[1314]: titan18:1094 Sep 18 07:45:01 titan XrootdFS[1314]: titan25:1094 I know that there was a connection problem because when trying to write into r/w xrootdfs file system I go this error: [Errno 110] Connection timed out: 'mc11_valid.113642.Pythia8JetsJ7.recon.log.e789_a124_tid365181_00' _______________________________________________________ Reply to this item at: <http://savannah.cern.ch/bugs/?86870> _______________________________________________ Message sent via/by LCG Savannah http://savannah.cern.ch/
