Hi,
I have another problem with XrdClientAdmin::XrdExistFiles using the
load balancer oprserv08. The following perl code snipped doesn't find a
file as it does not get redirected:
XrdClientAdmin::XrdInitialize("root://oprserv08:1094//prod", 2);
if (XrdClientAdmin::XrdExistFiles("/prod/foo/test.01.root")) {
# is never true
}
However, adding a XrdClientAdmin::XrdChmod before the 'if' statement
like
XrdClientAdmin::XrdChmod("/prod/foo/test.01.root", 0x6, 0x4, 0x0);
results in being redirected and the following
XrdClientAdmin::XrdExistFiles then evaluates correctly.
This is of course quite an ugly hack.
Cheers,
Remi
