No, it doesn't make sense. Why would you want to enforce quotas for root?

Why would you want to enforce quotas for root? A week ago I tried this and project quotas appear to apply to root.

Granted, that is not a *user* exception. Correct, and again by intent and design as project quotas are optional. i.e. there has to be some way of ensuring non-project ID controlled files won't have quota enforcement applied to them. ;) Cheers, Dave. -- Dave Chinner david@fromorbit.com _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 11+ messages in thread

I considered the documentation to be slightly misleading where is says soft and hard limits are never applied to the root user. The project quota does have a soft and hard limit. The soft limit, seemed not to apply to the root user - at least there was no soft limit warning anywhere when it was busted.

Since at the time I was also testing Btrfs stuff I’m going to say it was at the oldest 3.17.1, and could have been 3.18rc1 or rc2.
