I am trying to set up the Composite Name Space and am having trouble. I am running xrootd 3.0.5 from the xrootd.org repo. I have a data server that runs two xrootd servers to export two separate namespaces, /srm and /atlasC. I have a single redirector that runs on port 1094 and handles requests for both /srm and /atlasC. This has been working fine for some time now. I have managed to get a cns xrootd server to run on the redirector and two XrdCnsd processes on the data server, both writing to /data/inventory. I have two problems. First, only the /atlasC namespace is being inventoried. Second, there is no evidence that the redirector is accessing the CNS xrootd. In particular, when the data server is heavily loaded, getting directory information still takes a long time. The redirector xrootd.cf: all.manager hn.at3f:1213 if exec cmsd xrd.port 1213 all.role manager else if named cns all.export /data/inventory xrd.port 1093 else all.export /srm all.export /atlasC xrd.port 1094 all.role manager fi The data server xrootd.cf: all.manager hn.at3f:1213 if named srm all.export /srm oss.localroot /disk/data3/ns-srm oss.space public /disk/data3/xrddata oss.space public /disk/data4/xrddata oss.space public /disk/data5/xrddata oss.space public /disk/data6/xrddata oss.space public /disk/data7/xrddata xrd.port 1094 fi if named atlasc all.export /atlasC oss.localroot /disk/data0/ns-atlasC oss.space public /disk/data0/xrddata xrd.port 1095 fi all.role server ofs.notify closew create mkdir mv rm rmdir trunc | /usr/bin/XrdCnsd -d -D 2 -i 90 -b hn.hep.upenn.edu:1093:/data/inventory Can I get this configuration to work?
