Ciao, on the CMS-Eu redirectors I implemented as explained here:
we have 2 redirectors (xrootd.ba.infn.it and xrootd-redic.pi.infn.it), under DNS RR xrootd-cms.infn.it

Now redirectors' configs read

all.role manager

The known managers

all.manager xrootd-cms.infn.it+ 1213
all.manager meta any cms-xrd-global.cern.ch+ 1098

which I understand is the advised solution. What I see is strange.
if I do something like

xrdcp -d 3 root://xrootd-redic.pi.infn.it//store/test/xrootd/T2_ES_IFCA/store/mc/SAM/GenericTTbar/GEN-SIM-RECO/CMSSW_5_3_1_START53_V5-v1/0013/CE4D66EB-5AAE-E111-96D6-003048D37524.root .

and I look into the logs, I see this goes
xrootd-redic.pi.infn.it:1094 -> xrootd.ba.infn.it:1213 ALWAYS
(so indeed xrootd-redic.pi.infn.it:1213 does not seem to be serving files at all).
If I switch off xrootd.ba.infn.it:1213, xrootd-redic.pi.infn.it:1213 starts to serve files, but as soon as I start again xrootd.ba.infn.it:1213, the latter gets all the traffic.

I tried with things like

all.manager any/all xrootd-cms.infn.it+ 1213

(never really understood the difference any/all, my fault ...), but this does not seem to change the picture

eventually, on xrootd-redic.pi.infn.it cmsd.log I see traffic (with
grep serving cmsd.log
) only when the other cmsd is down ... is this expected? is there a way to make sure

all.manager xrootd-cms.infn.it+ 1213

balances the cmsd calls between RR-DNS hosts?

thanks

tom
