//   a. open a non-ROOT generic file
   //      "root://server1:port1[,server2:port2,...]/pathfile?filetype=raw"

as a way to instruct the client to probe more than 1 server.

but if I try it, it does not seem to work:

[a07cms04@r113c02s03 CMSSW_11_1_2]$ xrdcp -f  'root://r171c01s01.marconi.cineca.it,r171c01s02.marconi.cineca.it///store/test/xrootd/T1_IT_CNAF/store/mc/SAM/GenericTTbar/AODSIM/CMSSW_9_2_6_91X_mcRun1_realistic_v2-v1/00000/A64CCCF2-5C76-E711-B359-0CC47A78A3F8.root' .
[0B/0B][100%][==================================================][0B/s]
Run: [FATAL] Invalid address

isn't is supported any more?

And, assuming it still works, I understand it is not a round robin between servers, but a failover to the second if the first is not ok.

Is there a way instead to use a random one between those provided, such that to implement a "client side" round robin?

thanks
