Manfred,

Thanks for the quick reply: your advice to use 'no_root_squash' solved my
problem.
I feel stupid because I read about that option but didn't understand what it
did...

Appreciate your help!
Mark

The chgrp and chown commands require root permission.
Add "no_root_squash" to /etc/exports on bigserver2.
See 'man 5 exports" for more details.

Or run chgrp and chown on bigserver2, not on smallserver1.
