You aren't doing anything wrong. Long arguments with customer support and
careful examination of the namespace code caused me to conclude the

1) multiple primary namespace servers for a particular namespace aren't
supported, whatever the documentation or namespace editor may make you want
to believe. The code just isn't there to keep >1 namespace server consistant
with each-other, nor correctly handle >1 disk copy of the namespace. (if
they only have 1 copy the "other" primary server doesn't lock it, so the two

2) Secondary servers aren't as useful as you might want them to be.
Basically, during boot, a machine will use a secondary server for some
things, but they have to time out on the primary first. Other things (like
you to wait until the primary is available, since it needs to get to

2) can only really be solved by moving more things into the namespace, and
the current implementation is probably already over-burdened (statice,
anyone?). solving 1) requires a small matter of programming, and not an
insignificant one IMHO.
