Hi Jerry,

Have you created both the volumes and mountpoints for them?

Wonder if there are some explanations on the Wiki, certainly were on the list.

Volumes are Codas "natural" units of data.

By volume you
 - setup replication
 - backup
 - set quota
 - repair conflicts
 - reintegrate changes
 - implicitely serialize some other operations

so you do not want them to be too big, it is going to be both inconvenient
and inefficient (slow).

Access control though is done per directory, not per volume.
