Description Jim Faulkner 2012-11-25 23:01:06 UTC

I'm unable to get net-fs/autofs-5.0.6-r3 to mount an NFSv3 or NFSv4 filesystem on my HPPA machine.  

NFSv4 example:
My auto.master:
/mnt/auto /etc/autofs/auto.portage --timeout=5 --ghost
My /etc/autofs/auto.portage:
portage         -fstype=nfs4,rw,intr    mrwendal.cs.yale.edu:/portage

automount debug output when I try to access /mnt/auto/portage:

I am able to mount NFSv4 filesystems fine, as the above comment demonstrates.  It seems that the problem is with autofs.

You're running a 64-bit kernel with a 32-bit userland - the linux-parisc mailing has a discussion about a kernel patch to address this issue, currently. Perhaps you could try the attached patch.

Comment 4 Jim Faulkner 2013-02-05 20:58:04 UTC

Confirmed, after building linux-3.7.6 with the patch from http://thread.gmane.org/gmane.linux.ports.parisc/4767 autofs works just fine.

This patch seems to be present in the 3.8 branch, upstream has also backported it to the 3.4 branch; this is not present in EOL kernels. I'll hear what the right approach to deal with this is, meanwhile you can apply it as an user patch until you can use the 3.8 branch.
