mount 2.12: proplist and failed mounts

mount 2.12: proplist and failed mounts

Hi,

I was happily using autofs 4.1.3 with mount 2.11y. The maps contained
the proplist option (we share the maps with some OSF1 boxes), but that
did not disturb.

for other reasons I had to upgrade mount to 2.11 (part of
util-linux). Suddenly autofs will not mount anymore with errors like:

Jun 25 12:25:50 heretic automount[12646]: failed to mount /home/thimm
Jun 25 12:25:50 heretic automount[12648]: >> Unsupported nfs mount option: proplist
Jun 25 12:25:50 heretic automount[12648]: mount(nfs): nfs: mount failure nukleon:/amd/nukleon/1/home/ag-linke/thimm on /home/thimm

I tested mount -o proplist and I got the above error and the exit code was 32:
# mount -o proplist nukleon:/amd/nukleon/1/home/ag-linke/thimm /home/thimm
Unsupported nfs mount option: proplist
# echo $?
32

OK, so I thought mount has become quite picky now, and downgraded. I
retried the manual mount and got the same error & exit code!

But autofs works properly again?!?

For one I'd like to understand how autofs manages to workaround this
error for 2.11y, and perhaps whether this can be used for mount 2.12,
also. Granted, the true error lies in the configuration asking for
unsupported proplist options, but since it had a nice and greceful
error fallback until now, it would be nice to keep it.

Thanks!

You need to specify the sloppy mount option (-s) for this to work.  It
basically tells mount to not be so picky about options it doesn't
understand.  (Note that autofs uses this option.)

As for your experience, were you using Red Hat packages per chance?  I had
a bug filed here (on FC2, I think) which described your situation.  The
problem was that someone (not naming names) accidentally committed some
code which did not allow sloppy mounts for NFS.  It has since been fixed.

Please let me know if you need more help tracking this down.

Thanks!

Jeff

Yes, I "backported" util-linux-2.12-18 (rawhide/fc2) to non-selinux
setups (needed to tweak the nfssloppy patch) ...

Now, that I know what to look for I found the bugzilla entry:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=122448

Looks like the fix is not yet in rawhide :( :( :(

BTW, here are my patches to make util-linux build again on non-selinux
systems:

I put together util-linux rpms which include

o the (no)selinux patches
o the sloppy fixes by Michael Young
o the [no]acl patches by Andreas Gruenbacher
  (http://bugzilla.atrpms.net/show_bug.cgi?id=73)

The work fine in mixed autofs'ed environments of OSF1s, acled and
non-acled NFS servers and acled NFS clients.

OK. I'm confused as well.

I'll play with some invalid options ove rthe weekend and see what I can 
do.
