NFS4 problems on Ubuntu 10.04 and Ubuntu Server 11.04

Question

I tried installing nfs-common on a Ubuntu 10.04 and on a Ubuntu Server 11.04 machines like this:

sudo apt-get install nfs-common

The /etc/init.d/nfs-common script does not get created. Also, the rpc.idmapd daemon did not start because of the /var/lib/nfs/rpc_pipefs/nfs directory missing.

I created the directory in question and idmapd now runs, but when I try to mount an NFS4 filesystem, the UID/GIDs do not get mapped correctly (they get mapped to 4294967294:4294967294), which means that there is a problem with idmapd, but the daemon is running and the configuration on both the server and the client is identical (in /etc/idmapd.conf).

I read that there was a "solved" bug with /etc/init.d/nfs-common not being created, but I am experiencing the issues still on Ubuntu 10.04 and Ubuntu Server 11.04. Does anyone have a solution?

Answer 1

I can only answer the part about /etc/init.d/nfs-common not being created. Ubuntu has moved from the traditional init to a new system called Upstart. You can manipulate Upstart services using the service command, e.g.:

$ sudo service nfs-kernel-server restart

Answer 2

In my case the 4294967294:4294967294 was solved by re-starting the idmap service on both the server and the client.
