Description Stefan Gohmann univentionstaff 2011-02-11 08:24:52 CET
Im ersten Schritt sollten wir es möglich machen NFSv4 Freigaben über den UDM anzulegen.

+++ This bug was initially created as a clone of Bug #7571 +++

Die meisten unserer Tools sollten mitlerweile NFSv4 können. Es gibt eine
Kurzanleitung zru Verwendung unter:


Dazu muss util-linux aktualisiert sein (#7570).

Folgende Bugs könnten mit NFSv4 behoben werden:
#3172 - 16 Gruppen
#7373 - NFSv4 Fehlermeldungen

Das wird für Ubuntu-Clients vermehrt angefragt, z.B. an 2012100121003629 und durch einen Partner. Ziel ist meist, das Fat Clients/stationäre Clients ihr $HOME im NFSv4 ablegen.

Wurde auch nachgefragt bei der Technikschulung in Stuttgart.

NFsv4 should be an option like NFSv3 and CIFS. NFSv4 and CIFS should be active  by default.
Comment 4 Erik Damrose univentionstaff 2013-10-16 14:22:48 CEST
NFSv4 is activated in UCS 3.2 with

r45165 univention-nfs 6.0.1-5.90.201310161401
Comment 5 Felix Botner univentionstaff 2013-10-21 17:10:54 CEST
OK - nfs/nfsd/nfs4 is true by default now, tested 
     some nfs clients (kubuntu, ubuntu, UCS 3.2, UCS 2.4)
     all could mount the share with the  "-t nfs4" option
     id mapping was ok

OK - Changelog
Comment 6 Felix Botner univentionstaff 2013-10-23 13:28:01 CEST
mount a nfs(4) share on an UCS 3.2 client takes about 10s, dmesg gives the following information

[ 1624.612153] RPC: AUTH_GSS upcall timed out.
[ 1624.612153] Please check user daemon is running.

if the GSSD is started on the client (NEED_GSSD=yes in /etc/default/nfs-common and /etc/init.d/nfs-common restart) the timeout is gone, see


Maybe we should add an ucrv nfs/common/gssd to configure NEED_GSSD in /etc/default/nfs-common  and set it to "yes" by default?
Comment 7 Erik Damrose univentionstaff 2013-10-24 11:47:39 CEST
nfs/common/gssd is now available and configures NEED_GSSD in /etc/default/nfs-common. The default value is 'yes'

r45555 univention-nfs 6.0.2-1.91.201310241144
Changelog updated
Comment 8 Felix Botner univentionstaff 2013-10-25 10:40:56 CEST
please add nfs/common/idmapd?yes
Comment 9 Erik Damrose univentionstaff 2013-10-25 10:54:38 CEST
as discussed, the idmapd option has been added in
r45584 univention-nfs 6.0.3-1.93.201310251052
changelog updated
