Unfortunately, this is not possible today, though I don't think it would be too hard for someone to implement this by copying "enable_remote_dir_gid" and similar checks on the MDS.

<div class="">In Lustre 2.14 and later, it is possible to set an OST pool quota that can restrict users from creating too many files in a pool. This doesn't directly prevent them from setting the pool on a directory (though I guess this _could_ be checked),
but they would get an EDQUOT error when trying to create in that directory, and quickly tire of trying to use it.</div>
