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.

Doc Text:
Cause: Consequence: Fix: After updating package, already existed symbolic links under /etc/rc.d are not updated and users are advised to run 'chkconfig ypbind resetpriorities' to apply new priorities defined in the updated package. Due to bug #887205 chkconfig doesn't updates only start priorities, which is sufficient in most cases. However, if we need to update kill priorities as well, we have to use 'chkconfig ypbind reset' and then 'chkconfig ypbind on' in case we want ypbind to start onboot. Result:

Description Shawn Stephens 2010-10-28 15:08:39 UTC 
We still have this in the RHEL 6.0 Beta 2.

We are having to change the order since it wasn't fixed.  We like to mount our Oracle database NFS shares via /etc/fstab, and since ypbind isn't up before netfs, the filesystems fail to mount since they are trying to lookup the hostname.  I guess we could put in the FQDN for the hosts, but we resolv NIS hosts first.

It's probably good practice to have all of your nsswitch resolv capabilities running before starting netfs.


+++ This bug was initially created as a clone of Bug #169036 +++

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050909 Red Hat/1.7.10-1.4.2

Description of problem:
The rc*.d links to /etc/init.d/ypbind are out of sequence.

For hosts that mount NFS file systems that reside on a server which is only resolvable through NIS, ypbind must start before netfs. 

The symptom is that some NFS file systems were not mounting during boot but could be mounted with no problems with 'mount -a' after the system was fully booted.

The fix is to renumber the symlinks for ypbind in /etc/rc*.d to be before netfs. On a stock RHEL4 system, the links are S27ypbind which follows S25netfs in the boot process. If ypbind links are renamed S23ypbind, all NFS file systems mount correctly at boot time.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. /etc/fstab has an nfs mount whose server name is only resolvable by NIS
2. boot or reboot
3.
  

Actual Results:  NFS file system does not mount during boot.

Following boot, mount -a will correctly mount the file system.

Expected Results:  All NFS file systems should mount during boot.

Additional info:

To fix this on our systems, after a clean RHEL4 install, we run:

cp /etc/init.d/ypbind /etc/init.d/ypbind.orig
chkconfig --del ypbind
sed 's/# chkconfig: - 27 73/# chkconfig: - 23 77/' /etc/init.d/ypbind.orig \
  > /etc/init.d/ypbind
chkconfig --add ypbind
chkconfig --level 345 ypbind


Ideally, S23 or S23 (or anything appropriate and before netfs) should be the RHEL default start order for ypbind so we don't have to apply this workaround after each install.

Is this still an issue?  It's very difficult to change service start ordering in the middle of a release.  We may need to move this to RHEL6.

Closing as there hasn't been any update in years.
Comment 2 Karel Klíč 2010-11-19 19:27:17 UTC 
S24 and K77 seem ok to me.
Comment 3 Karel Klíč 2010-11-19 19:30:26 UTC 
Correction: S24 and K76.
