Not really,

My interpretation is that all files written with group2 will count  
towards the quota on that group. However any users with group2 as the  
primary group will be prevented from writing any further when the  
group2 quota is reached. However the culprit user1 with primary group  
as group1 won't be detected by gpfs, and can just keep going on  
writing group2 files.

As far as the individual user quota, it doesn't matter: group1 or  
group2 it will be counted towards the usage of that user.

It would be interesting if the behavior was more as expected. I just  
checked with my Lustre counter-parts and they tell me whichever  
secondary group is hit first, however many there may be, the user will  
be stopped. The problem then becomes identifying which of the  
secondary groups hit the limit for that user.
