I'd try this: redirector: xrootd.trace emsg login stall redirect xrd.trace conn cms.trace defer files redirect stage server: # For debug, to see files being searched # cms.trace defer files redirect stage cms.trace defer redirect stage You say xrdmapc shows the configured servers, right? We had some trouble with ipv4/6 at ucsd lately, clients will be redirected to ipv6 servers only if they come in via ipv6 to the redirector. Can you restart redirector cmsd and then (after 30sec) look at: [1131] root@xrootd /var/log/xrootd/xcacheucsd# grep Routing cmsd.log | sort =====> Routing for bcache-1.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for bcache-1.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-00.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-01.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-02.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-03.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-04.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-05.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-06.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-07.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-08.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-09.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xcache-10.t2.ucsd.edu: local pub4 prv4 =====> Routing for xcache-11.t2.ucsd.edu: local pub4 prv4 pub6 prv6 =====> Routing for xrd-cache-1.ultralight.org: local pub4 prv4 pub6 prv6 =====> Routing for xrd-cache-2.ultralight.org: local pub4 prv4 pub6 prv6 Matevz On 2019-12-02 11:24, Sam Skipsey wrote: > No, I explicitly did that.
