Unfortunately loglevel 10 changes the dynamics and the error doesn't happen,
as you thought. I have attached some sample SrvLogs anyway.

I will send more stuff when I can generate something useful - I'm under a
bit of pressure at the mo but I'll get to it.

I have also spotted what I think is a mistake in the code that is preventing
things like 'cfs fr <dir>' from working properly. Source release coda 6.0.6:
file, line 1002: looks like it's missing a 'break' to me.
Result is that code that operates correctly in the VIOC_SYNCCACHE case falls
through into VIOC_REDIR and the return value is changed to EINVAL, unless
your directory string happens to be the same size as a struct in_addr, in
which case venus will probably crash.

Sorry if it's already been fixed.
