As part of the updates to and ongoing improvements of the /scratch filesystem, we have moved to using project quotas instead of group quotas at the filesystem level. This means that usage will be metered and quotas enforced based on the contents of a project's directory there, rather than the group ownership. The chief advantage of this change is that it more-closely reflects "expected" behaviour: the objects that count towards the /scratch usage of project ab12, for example, will be precisely those within /scratch/ab12.

There are no changes to the enforcement of quotas for the /g/data filesystems: these all still use group quotas (except for gdata5, which already uses project quotas).

There is no change to the command line tools that users will use: lquota will automatically report on project quotas instead of group quotas where appropriate. However, if you're using the nci-files-report tool to provide a breakdown of the usage for /scratch we now recommend using the -p ("project directory") filter option rather than -g ("group").
