Hi,
I have a number of Linux clients (Ubuntu 10.04) that mount a (read-only)
directory from 3 replicated servers using NFSv3. I am now in the
process of moving to NFSv4. I can mount the directories using NFSv4
manually. I can mount the directories using autofs over NFSv4 when I
specify only 1 server (any of the 3 will work), but when I add all 3
servers to the automount configuration file the mount fails.
The configuration files look as follows:
# /etc/automaster
/- /etc/auto.local
# /etc/auto.local
/usr/local
-fstype=nfs4,ro,nodev,nosuid,nonstrict,nodev,sync,_netdev,proto=tcp,retry=10,rsize=8192,wsize=8
192,soft server1:/local/ubuntu64 server2:/local/ubuntu64
server3:/local/ubuntu64
(Note: the content of /etc/auto.local is on 1 line but my e-mail
application is splitting the content over multiple lines)
As I said above a similar setup using nfs in stead of nfs4 works fine,
specifying only 1 server works fine too.
If I run automount manually with verbose and debugging enabled I see the
following output when trying to access /usr/local:

Any idea what might be going wrong?
Thanks in advance,
