> While trying to create NFS (I execute the following): > [root@LH20-GPFS1 ~]# mmnfs export add /fs_gpfs01 -c "* > Access_Type=RW,Protocols=3:4,Squash=no_root_squash)" You can get away with little to no authentication for NFSv3, but not for NFSv4. Try with Protocols=3 only and mmuserauth service create --type userdefined that should get you Unix-y NFSv3 UID/GID support and "trust what the NFS client tells you". This of course only works sanely if each NFS export is only to a set of machines in the same administrative domain that manages their UID/GIDs. Exporting to two sets of machines that don't coordinate their UID/GID space is, of course, where hilarity and hijinks ensue....
