put all WNs (with their full local host.localdomain name ) in CE's
/etc/hosts.equiv ?
try briefly mode 700 with no_root_squash, restart nfs server.
I so this problem at TAU-LCG2, they mount pool directories via nfs,
without no_root_squash, and mode 755 and PBS works; if the mode is set
to 700, then you have to export with no_root_squash, restart nfs server
and again PBS works. I know it for sure.
