With patch level 3.1.3A pnfs allows to specify the behaviour
of level 1 to 7 on the creation of a file and on the
modification of its attributes. Usually the levels behave
as needed at DESY, which means, level 1, 2 and 7 are
in sync with the top level and the residual levels
remain unchanged on chmod or chown ... commands.
With Patch 3.1.3.A a new /usr/etc/pnfsSetup variable
has been added which defines which level keeps in sync
with the top level and which levels remain unchanged.
Syntax : levelmask=0:x:x:x:x:x:x:x
x : -1 in sync with top level
0 uid=0;gid=0;mode=700
