Why XROOTD does not select the free file server to write?

ROOT
1

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.

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.

set xrdr = valtical.cern.ch
cms.allow host valtical00.cern.ch
cms.allow host valtical04.cern.ch
cms.allow host valtical05.cern.ch
cms.allow host valtical06.cern.ch
cms.allow host valtical07.cern.ch
cms.allow host valtical08.cern.ch
cms.allow host valtical09.cern.ch

I changed the path from valtical to valtical00, e.g. writing to that file server directly.  then the uploading get succeeded. But why xrootd does not select valtical00 to write?

Dear Expert:

After checking the log I found that two disks (localdisk3 and localdisk4) on valtical00 were not taken into account when xrootd starts up:

But actually localdisk3 and localdisk4 are configured in the configuration file /opt/vdt-xrootd/xrootd/etc/xrootd.cfg:

    all.role server

    oss.cache public /localdisk5/xrootd xa
    oss.cache public /localdisk6/xrootd xa
    oss.usage log ${xrootdlocation}/var/admin

any idea ?
