Dear Expert:

    Today when I try to upload some files, the following error appeared:

root://valtical.cern.ch//localdisk/xrootd/test1.root

Last server error 3011 ('No servers are available to write the file, 
however, on one file server there are still ~ 5TB free space.

valtical.cern.ch is the xrdr, while valtical00 is one of the disk 
servers which has a lot of free space, the other disk servers are all 
full at this time.

Here is the xrootd configuration file on valtical00:
------------------------------------------------------------------------------------------------------------------------

xrootd.fslib ${xrootdlocation}/lib/libXrdOfs.so

if $(xrdr)
         all.role manager

         # CNSD_XRDR_BEGIN
         # broadcast mv, rm, rmdir and trunc operations to all data 
servers, and
         # redirect the client to CNS (the second xrootd instance on 
redirector)
         # to do the operation on shadow file/dir.
         ofs.forward 3way $(xrdr):2094 mv rm rmdir trunc
         # CNSD_XRDR_END
else

         all.role server
         xrootd.chksum max 3 adler32 ${xrootdlocation}/bin/xrdadler32
         cms.perf int 2m pgm ${xrootdlocation}/etc/XrdOlbMonPerf 120
         set osscachepath = /localdisk/xrootd
         oss.cache public $(osscachepath)/* xa
         oss.cache public /localdisk2/xrootd xa
         oss.cache public /localdisk3/xrootd xa
         oss.cache public /localdisk4/xrootd xa
         oss.cache public /localdisk5/xrootd xa
         oss.cache public /localdisk6/xrootd xa
         oss.usage log ${xrootdlocation}/var/admin

         # CNSD_BEGIN
         ofs.notify create closew mkdir | ${xrootdlocation}/bin/XrdCnsd 
-d -l ${xrootdlocation}/var/logs/cnsd.log root://$(xrdr):2094
         ofs.notifymsg create $TID create $FMODE $LFN?$CGI
         ofs.notifymsg closew $TID closew $LFN $FSIZE
         # CNSD_END
--------------------------------------------------------------------------------------------------------------------------------------

As you see, on valtical00 we still have 3 disks empty
[valtical00] /afs/cern.ch/user/q/qing > df -h | grep localdisk
/dev/sdb1             1.8T  1.7T     0 100% /localdisk
/dev/sdc1             1.8T  1.7T     0 100% /localdisk2
/dev/sdd1             1.8T  192G  1.6T  11% /localdisk3
/dev/sde1             1.8T   43G  1.7T   3% /localdisk4
/dev/sdg1             1.8T  1.7T     0 100% /localdisk5
/dev/sdh1             1.8T  196M  1.7T   1% /localdisk6

   Any idea what can be done to use these 3 disks?

   Cheers,Gang
