Hi Wei, Thanks for your reply. Here are the fqdn of one data server, one manager and one supervisor : server : g26n03.hep.wisc.edu <http://g22n02.hep.wisc.edu/> manager : cmsxrootd.hep.wisc.edu <http://cmsxrootd.hep.wisc.edu/> supervisor : s15n01.hep.wisc.edu <http://s15n01.hep.wisc.edu/> xrootd config file is same for all these and roles are defined inside the config files. Both cmsd and xrootd depends on the same ‘/etc/xrootd/xrootd.cfg’ file. Please find it in the attachment. -Tapas (T2_Wisconsin admin) > On Apr 3, 2015, at 11:06 AM, Yang, Wei <[log in to unmask]> wrote: > > Hi Tapas, > > A number of us are on vacation, including me.
