[lustre-discuss] Restricting sub directory mounts/access

One way I was thinking of doing this was using nodemap to map the UID/GID of the user to root or nobody so access to the compliance data is limited a root alone. Although this could work, I was looking for alternate ways to mount or access is restricted by IP if it was possible.

Thank you,

Dear All,

Wondering if I could restrict access to a specific directory from within my lustre file system, for example /scratch/group/data_dir "on a set of nodes"?
I would still want to have full read-write access to other directories( /scratch/group/<other_dirs>).

Can this be achieved in some creative way using overlayFS?

Thank you,
