[gpfsug-discuss] Fileset quotas enforcement

Did you try to run mmcheckquota on the device

I observed that in the most recent versions (for the last 3 years)  
there is a real long lag for GPFS to process the internal accounting.  
So there is a slippage effects that skews quota operations.  
mmcheckquota is supposed to reset and zero all those cumulative deltas  
effective immediately.
