[gpfsug-discuss] BIG LAG since 3.5 on quota accounting reconciliation

[Jaime Pinto]

Just bumping up.
When I first posted this subject at the end of March there was a UG  
meeting that drove people's attention.

I hope to get some comments now.

Thanks
Jaime

> More recently we adopted a G200 appliance (1.8PB), with v4.1, and now
