Just chiming into to reinforce Åke’s response.  We also solved the problem in the same way Åke described.

Hello Åke.

Thank you for confirming our suspicion.
We have come to the same conclusion on our larger systems (DDN & Clusterstor) but we were hoping perhaps in newer lustre versions this was different.

User quota, if enabled, will be affected regardless of where in the file system the file is.

We decided to use only project quota, even for users home directory, i.e. $HOME get projectquota for projid = userid and project storage has projid = the project storage gid.

Made our life easier

Subject: [lustre-discuss] question regarding lustre project quotas vs user and/or group quota

Hello all

I have a question regarding project quotas

If we have activated user and project quotas on a file system:
Will user quota be affected by what is inside a project/directory quota?
How can we prevent user quota being affected by what a user put into a directory/project quota

This is on lustre 2.15.x

Best Regards
Eianr Næss Jensen
