Have you tried a > 'cat /proc/mounts' to check that the partition is indeed mounted as > NFSv3 when reading the ACLs fails? Yes, it definitely is mounted with v3. Here's sth. new I found out this morning: It looks like the _first_ NFS mount from the server does not get ACLs. I.e., when I switch the order of the entries so that /rpm is mounted first, /home second, then the ACLs are visible on /home but not on rpm. I added a second NFS server with one export and activated ACLs there, and it's still the same: Whichever of the three mounts comes first does not have ACLs until it is unmounted and remounted. So if the new NFS mount entry comes first on the client, both /rpm and /home will have ACLs. So this looks more like a client bug to me, because it is not always the first mount from the same server that does not have ACL, but the first overall NFS mount. Like the client was not able to initialize ACLs for NFS before the first mount is done... I will check a recent kernel on the client side. cu, Frank -- Dipl.-Inform.
