No, because it uses soft quotas.

What I do is set the soft quota at 95% of the hard quota and use it to 
indicate that people are running low, it is fed into zenoss. The grace 
period is then set really high (3000 days was about as high as it would 
go reliably) with the actual limit and the charge back to the users 
being based on the fileset hard quota. The advantage of this method is 
that the alert in zenoss is triggered by an SNMP trap which is better 
than polling every five minutes.

Therefore I continue to use my mmdfree command that I wrote which is 
based of hard quotas. I admit my usage of hard and soft quotas is rather 
unusual but it does works well.
