If I do not do that, I see no effect at all1 - 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 havexrd.port anyis 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.cfgxrd.port anyall.role supervisor# The known managersall.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 clustercms.allow host *# Logging verbosityxrootd.trace emsg login stall redirectofs.trace all -debugxrd.trace all -debugcms.trace all -debugOn 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. This is well cared of within recent fixes I believe. I don't recall details right now but can search through if needed.
So, feel free remove the line "xrd.sched maxt 16000".

Ciao, I am trying to see if there is the need for a supervisor on one of
our CMS EU redirs.
In the logs, I never really see anything like 'If you suspect this,
check the manager’s log. It will contain warnings about orphaned data
servers'
so I am not sure we have a problem, but still we a re very close to the
64 limit so better to be proactive.
What I want to do as step #1 is to run the supervisor as an additional
daemon on the redirector (it is a test, I really want to see what
happens first, and the machine is big so should not be an issue)
I looked at the documentation below, but I have to admit it is a bit
obscure (to me).
So, I have a cmsd/xrootd (the eu redir) running on ports 1213/1094, and
redirecting "up" if needed (to the global redirector).
Starting from their config, I just wanted to prepare a config for the
supervisor.
The minimal one I am trying to guess from the documentation would be
===
xrd.port any
all.role supervisor
# The known managers
all.manager xrootd.ba.infn.it <http://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
cms.fxhold 8h
xrd.sched maxt 16000
===
but again , this is a sort of guess .... Do you have an example of a
standalone cfg file for a supervisor?
thanks
tom
