I feel stupid not knowing this, but alas, I need to ask.

I have a few directories being automounted via NFS on my CentOS boxes. Source is a Dell NAS or Openfiler (which we are working on migrating from). The default owner.group is root.root with 755 perms. I want to modify default group and the default perms. I can chmod the directory no problem, but as soon as I reload the maps, perms fall back to default.

Default group is mapped using export file option anongid used with a squashing option (all_squash or root_squash). The default permissions are given by your umask value. UIDs must be consistent between the NFS client and the NFS server.
