[Lustre-discuss] More Efficient Method of Messuring Usage?

[Mike Hanby]

Jason / Guy thanks for the suggestions.

We may go ahead and enable quota since we'll need them at some point.

Robinhood looks interesting since the next logical step is what do you do when the disk report shows certain users abusing the FS. And again the traditional tools don't scale well to TB worth of storage.

Thanks for sharing that link,

Mike

As Guy suggested, quotas are probably the quickest path to solution.

If you don't want to enable them for some reason, RobinHood might do  
the trick for you:

You can use it to monitor utilization without using the purge  
functionality. I've looked into using it for this purpose, but I  
haven't tried it yet.
