Using Apple Qmaster with an NFS Server
By default, Apple Qmaster uses /etc/exports to define its Cluster Storage export. This can
cause a conflict if you defined an NFS export in your local NetInfo database. When you
enable a controller using Apple Qmaster 2 or later, Apple Qmaster uses /etc/exports, not
entries defined in your NetInfo database. To work around this issue, either move the
exports to /etc/exports, or move the controller to a computer that doesn’t export anything.
