Hello,
we have the followoing problem: when we try to open the root file (on
Castor) via rfio. When we try to do this from local cern PC (having done
klog) it fails, while from lxplus it works. Does anybody have experience
with such operations? What can be the problem?
Below are the screenshots of failed (on local pc) and successful (lxplus)
trials.
Bets regards,
Ruben Shahoyan
