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.
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.

In specific, can we limit the following command so that it can be run by root only? lfs setstripe --pool myfs.mypool test_dir I would need something similar to what can be done for remote directories: lctl set_param mdt.*.enable_remote_dir_gid=1 Regards, Marco Passerini Cheers, Andreas -- Andreas Dilger Lustre Principal Architect Whamcloud
