ciao, the supervisor (started by hand with 'cmsd -d -l /var/log/xrootd/superv.log -c /etc/xrootd/xrootd-redir-cms-superv.cfg -k 7' and 'xrootd -d -l /var/log/xrootd/superv-x.log -c /etc/xrootd/xrootd-redir-cms-superv.cfg -k 7' ) fileis below * in the manager cmsd.log I just see: 150828 14:08:52 28267 XrdSched: running main accept inq=0 150828 14:08:52 27343 ?:80@xrootd XrdPoll: FD 80 attached to poller 1; num=22 150828 14:08:52 27343 Protocol: Primary supervisor.28781:80@xrootd:33530 logged in suspended. =====> Routing for xrootd.ba.infn.it: local pub4 prv4 =====> Route all4: xrootd.ba.infn.it Dest=[::90.147.66.75]:33530 while in the supervisor cmsd log I see 150828 14:08:52 28799 Pander supervisor services to xrootd.ba.infn.it:1213 150828 14:08:52 28799 Pander trying to connect to lvl 0 xrootd.ba.infn.it:1213 150828 14:08:52 28799 XrdInet: Connected to xrootd.ba.infn.it:1213 150828 14:08:52 28820 XrdXeq: Worker thread started 150828 14:08:52 28799 Add xrootd.ba.infn.it to manager config; id=0 which seems good, but then a series of: ... 150828 14:08:54 28799 manager.0:25@xrootd do_StateFWD: *Path find failed for state* /store/test/xrootd/T2_MY_UPM_BIRUNI/store/mc/HC/GenericTTbar/GEN-SIM-RECO/CMSSW_7_0_4_START70_V7-v1/00000/D00E55FF-F6CC-E311-9B51-02163E00E88E.root 150828 14:08:54 28799 Dispatch manager.0:25@xrootd for state dlen=148 150828 14:08:54 28799 manager.0:25@xrootd do_State: /store/test/xrootd/T2_MY_UPM_BIRUNI/store/mc/HC/GenericTTbar/GEN-SIM-RECO/CMSSW_7_0_4_START70_V7-v1/00000/4463C61D-03CD-E311-AF1A-02163E00F338.root 150828 14:08:54 28799 manager.0:25@xrootd do_StateFWD: *Path find failed for state* /store/test/xrootd/T2_MY_UPM_BIRUNI/store/mc/HC/GenericTTbar/GEN-SIM-RECO/CMSSW_7_0_4_START70_V7-v1/00000/4463C61D-03CD-E311-AF1A-02163E00F338.root ... and nothing else. So I have a few questions 0 - very naive: for the supervisor do I need to start cmsd AND xrootd? If I do not do that, I see no effect at all 1 - is the erorr expected with my config ? 2 - I did not set explicitly the port numbers to the supervisor, and they of course cannot be 1094/1213 since they are already taken by the manager. I just have xrd.port any is that enough? 3 - should I see some servers being "moved" by the manager to the supervisor? 4 - atm I have not opened any additional port on the firewall, since with 'any' I do not know which port will be used. Should I open something? thanks a lot and sorry for all the questions *: [root@xrootd xrootd]# cat /etc/xrootd/xrootd-redir-cms-superv.cfg xrd.port any all.role supervisor # The known managers all.manager xrootd.ba.infn.it 1213 # Allow any path to be exported; this is further refined in the authfile. all.export / r/w # Hosts allowed to use this xrootd cluster cms.allow host * # Logging verbosity xrootd.trace emsg login stall redirect ofs.trace all -debug xrd.trace all -debug cms.trace all -debug On Thu, Aug 27, 2015 at 5:26 PM, Marian Zvada <[log in to unmask]> wrote: > Hi Tom, > > I haven't tried it though, but looks good to me. > > One more thing, we should not use thread limit by hard from whatever > v4.x.x version, I think.
