dfreport

This attribute specifies the method for calculating free disk space. If you set it to all, the default, TAS reports all free disk space on all partitions to clients. Systems that do not support the UNIX statfs() system call or its equivalent do not support this options. If you set this attribute to root, TAS reports only the free disk space on the partition in which the virtual root of the client's connection resides. A freespace report attribute in a user's configuration file can override this attribute.

Usage:

tnservice -M -r realm -s service -a dfreport={all|root}
