Another words, if my independent fileset quota is 2GB, I should not be allowed to set quotas for it's dependent filesets more then 2GB ( for the dependent filesets created in aggregate ) ?<br><br>Thanks for your help!<br><tt><font size="2">_______________________________________________<br>gpfsug-discuss mailing list<br>gpfsug-discuss at spectrumscale.org<br></font></tt><tt><font size="2"><a href="http://gpfsug.org/mailman/listinfo/gpfsug-discuss">http://gpfsug.org/mailman/listinfo/gpfsug-discuss</a></font></tt><tt><font size="2"><br></font></tt><br><br><BR>
