Thank you for the response. We have been able to make some headway on
this, but I am still bumping up on some issues. It looks as if, when an
NFSv4 ACL is already present on the parent directory tree, copying acls
via robocopy works. However, if there is a posix ACL present, then the
ACLs are still not copied correctly. I was interested in setting the ACL
mode to nfs4 only (currently set to all), however, I have some
reservations about this.
The NFS server is Red Hat, and I need to be able to server version 3 and
version 4, plus we will have native GPFS clients and the CIFS clients.
What are the ramifications, in this setup, of changing the ACL type? What
would happen to any existing ACLs?
