# In this configuration file:
#
# 0) griddev20:1094 is the redirector. griddev20:1095 is the cnsd xrootd,
#    and griddev18 and 19 are data servers.
#
# 1) Use cmsd instead of olbd (the olbd is deprecated and won't work for us).
#
# 2) Data servers forward create, mkdir and closew (close on write) to the CNS
#    xrootd via the ofs.notify.
#
# 3) Redirector forwards mv, rm, rmdir and trunc to data servers, and redirect 
#    the client to CNS xrootd for the same operation.
#
# 4) Does not support Xrootd space tokens. However, ofs.notify will forward token
#    info to the CNS xrootd.
#

#--> Set "apath" to tell xrootd where to put special files created during
#    execution. We normally put this in /var/adm/xrootd as this is the safest
#    location. However, you will need root privileges to create the path.
#    If you can't, specify the path some other created path.
#
set apath = /var/adm/xrootd

#--> Set "logdir" to be where you want log files to be placed. You will need to
#    create this path.
#
set logdir = $(apath)/logs

# Below are all of the paths to be exported by the XrdCns xrootd. Change the
# paths as needed.

all.export /atlas/xrootd/usr
all.export /atlas/xrootd/atlasdatadisk
all.export /atlas/xrootd/atlasmcdisk

#--> Set "osscachepath" to be where the xrootd data space is rooted. Symlinks
#    will be created from the exported name space to files rooted in this
#    directory (i.e., the data space). This allows us to support space tokens
#    and quotas.
#
set osscachepath = /atlas/xrdcache

#--> Set "xrdr" to be the fully qualified name of the host that runs your
#    redirector.
