Bug 462278

+++ This bug was initially created as a clone of Bug #448936 +++

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b5) Gecko/2008032620 Firefox/3.0b5

Description of problem:
When running 'find' on a sub-directory (only one level down) of an automount (using NFS), the find returns "No such file or directory" on the first attempt, but then works fine on the second attempt.  So it occurs every time the directory isn't mounted.

Quick Example:
auto_master:
/home/test auto_test
auto_test:
dir  host:/my/test/&

find /home/test/dir/subdir - fails with "find: /home/test/dir/subdir: No such file or directory"
find /home/test/dir - works
find /home/test/dir/subdir/otherdir - works

Error message:
do_mount_indirect: indirect trigger not valid or already mounted /home/test/dir/subdir



Version-Release number of selected component (if applicable):
autofs-5.0.1-0.rc2.88, kernel-2.6.18-92.el5

How reproducible:
Always


Steps to Reproduce:
1. Setup an NFS export
2. Create an automount (we're using NIS+ with niscompat)
3. Run 'find' on a sub-directory of that mount

Actual Results:
find: /path/to/subdir: No such file or directory

Expected Results:
A listing of found files should have been returned.

Additional info:
This was on a 5.1 system, with the kernel and autofs updated to the 5.2 versions.

I have the the output from automount run in debug mode, but I would need the bug
to be private as it contains sensitive data.

Is there any movement on this bug.  I believe I am having the same issue.

Yes, but it's being worked on in another bug.
I believe this is a kernel bug and I have patches to address
it but I'm not sure how to make a test kernel available?

Which other bug is this being worked on?  I'd like to track it.

I don't think that bug is public, sorry.

The current status is that I have identified a mistake in the
patches and I'll be building test kernels soon. We will just
need to find a way to make them available to you for testing.

Unfortunately, there have been a few really difficult issues
reported recently and I'm struggling to fix them.

Sorry for the delay and inconvenience.
I'll get back to this bug as soon as I can.

Ian

Has a test kernel which includes a fix for this problem been built yet?

It has, how can I make it available to you?

Ian,

Could you place it on an http or ftp server?

Should have asked, what arches?

I've built and uploaded kernels for i686 and x86_64 to
http://www.kernel.org/pub/linux/kernel/people/raven/autofs

The corrections for this bug are covered by the changes
committed for bug 452139.

Don Zickus has included these patches in the test kernel
kernel-2.6.18-107.el5 which can be download from
http://people.redhat.com/dzickus/el5.

Thanks Ian.  I've tested Don's kernel build (x86_64), and verified that it did fix the problem.
