This may sound dumb but I am asking because I think there is an easy solution to this before I scratch my head too much.
We have a SAN with a filer on top that provides NFS share for other servers.
ServerA and ServerB have this share NFS mounted with no_root_squash. ServerA has userA on it which owns a folderA on NFS NAS. ServerB has UserB on it which needs write access to folderA.
is the solution to create a NFSUsers group on all servers and chgrp the folder to that or is there any other way?
