You need to remove the "*.pyc" files from /usr/lib/lustre and
/usr/lib64/lustre.

Presumably you tested on i386 before.

Newer versions of Lustre have /usr/lib64/lustre first in the lconf/lmc
libpath for python.

Hello,


I''m  testing a very simple ("local") lustre configuration
which is=20
generated by the following script. Unfortunately, lconf stops with an=20
error message ("AttributeError: LustreDB_XML instance has no attribute=20
''get_lov_tgts''") an I unfortunately can''t spot
the problem.

Thanks!
