RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHSA-2013:0496 0 normal SHIPPED_LIVE Important: Red Hat Enterprise Linux 6 kernel update 2013-02-20 21:40:54 UTC

Description Ian Kent 2012-10-15 00:53:48 UTC 
Description of problem:
When using the browse option a mount fail when accessing an
automounted directory results in the attributes of the directory
(owner, group, mode, access time) are being listed as unknown.

Version-Release number of selected component (if applicable):
All kernel versions.

How reproducible:
Always with the steps below.

Steps to Reproduce:

Make sure you have BROWSE_MODE="yes" in /etc/sysconfig/autofs.

1. Add a simple indirect mount map (it's required that
   the server does NOT export the /notexported directory):

# cat /etc/auto.master
/nfs    /etc/auto.nfs

# cat /etc/auto.nfs
v2      server:/notexported

2. Restart AutoFS and try to access the directory:

# cd /nfs/v2
-bash: cd: /nfs/v2: No such file or directory

3. List the contents of the indirect mount directory.

# ls -la /nfs
ls: cannot access /nfs/v2: No such file or directory
total 4
drwxr-xr-x  3 root root    0 Sep 24 21:43 .
drwxr-xr-x 28 root root 4096 Sep 24 21:25 ..
d?????????  ? ?    ?       ?            ? v2


Actual results:
As above in step 3.

Expected results:
Sensible attributes, in this case attributes of the directory
as they should be in the autofs file system.
