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.

Description Bill Nottingham 2010-05-13 20:19:38 UTC 
+++ This bug was initially created as a clone of Bug #589710 +++

Description of problem:
The ntpdate and netfs scripts (at least) run before NetworkManager
has configured networking.

Version-Release number of selected component (if applicable):
initscripts-9.12-1.fc13.x86_64
ntpdate-4.2.6p1-1.fc13.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Have a system network connection
2a. Have an nfs filesystem in /etc/fstab
2b. Have ntpdate run, possibly with a fqdn in /etc/ntp/step-tickers
3. Boot on a machine with sufficient cores to get the services starting
   up all at once.  I have 8 cores here.

Actual results:
ntpdate and nfs report [FAILED] due to nfs lookup failures.

Additional info:
Adding /usr/bin/nm-online -q somewhere in the scripts is probably the
right thing to do to delay their execution until the network comes up.
Although surely some sort of error checks are warrented as well.

Gah. s/nfs/dns/ lookup failures.

--- Additional comment from notting on 2010-05-06 15:18:02 EDT ---

netfs has a /etc/NetworkManager/dispatcher.d dispatcher script that kicks it once NM has an address. I don't think ntp does.

netfs also has a check:
   start)
        [ ! -f /var/lock/subsys/network ] && [ ! -f /var/lock/subsys/NetworkManager ] && exit 0

but that doesn't mean the address is configured, of course.

--- Additional comment from rth on 2010-05-06 16:46:17 EDT ---

Perhaps we could add a "nm-online -x" check to the end of that test sequence
(and possibly move that whole sequence into /etc/init.d/functions)?  That
might at least make the initial running of S25netfs exit properly.

The state of affairs at the moment is somewhat disconcerting...

--- Additional comment from rth on 2010-05-06 16:54:09 EDT ---

... Something like

__networking_enabled() {
  if [ -f /var/lock/subsys/network ]; then
    exit 0
  fi
  if [ ! -f /var/lock/subsys/NetworkManager ]; then
    exit 0
  fi
  /usr/bin/nm-online -x
}

...
  start)
    __networking_enabled || exit 0

Comment 4 Miroslav Vadkerti 2010-09-24 08:16:09 UTC 
VERIFIED as fixed in initscripts-9.03.17-1.el6.

netfs now doesn't fail at boot. Though ntpdate still does. I assume according to comments this is expected.

NEW PACKAGE:
[snip]
[No mention of Mounting NFS filesystems]
[snip]
ntpdate: Synchronizing with time server:        [FAILED]
[snip]

OLD PACKAGE initscripts-9.03.5-1.el6:
[snip]
Mounting NFS filesystems:  mount.nfs: Failed to resolve server nest.test.redhat.com: Name or service not known
mount.nfs: Failed to resolve server curly.devel.redhat.com: Name or service not known
                                                           [FAILED]
