[Bug 607039] Re: NFS4 automount using replicated servers doesn't work

[Stefan Bader]

Doh! I think I found out what it going on... The problem can be, as it
has been said before, reduced to attempting a NFS mount with:

mount -tnfs4 <server>:<path> <mntpt>

which will fail with a completely useless message of no such device. It
was also said that -tnfs does work. Now the interesting thing is that
*after* one successful run with -tnfs, the -tnfs4 does *also* work. I
must admit it took me a while to think of module loading. But that was
the solution in my tests. Apparently a mount -tnfs automatically loads
the nfs module, which does not work for -tnfs4 (I guess because there is
some glue missing to tell the system that the nfs module is the correct
one for both).

Could those affected try a quick work-around, please? Create a new file name /etc/modprobe.d/nfs4.conf with the following
content:

alias nfs4 nfs

In theory this should make sure the module gets autoloaded and the nfs4
autofs setup should be working...
