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.

bootchart

Description of problem:
In some environments network initialization takes a long time (slow DHCP, etc). When nsslapd-listenhost is configured, dirsrv systemd service fails to start, because it doesn't wait for the network to be available (see attached bootchart)

Only dirsrv.target waits for the network.service. To make it more confusing, dirsrv.target reports that it's active, though no instances of dirsrv have been started:

[root@rhel7ds ~]# systemctl status dirsrv.target 
● dirsrv.target - 389 Directory Server
   Loaded: loaded (/usr/lib/systemd/system/dirsrv.target; enabled; vendor preset: disabled)
   Active: active since Sat 2016-02-27 11:35:14 CET; 5min ago

[root@rhel7ds ~]# systemctl status dirsrv -l
● dirsrv - 389 Directory Server rhel7ds.
   Loaded: loaded (/usr/lib/systemd/system/dirsrv@.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Sat 2016-02-27 11:35:14 CET; 5min ago
  Process: 728 ExecStart=/usr/sbin/ns-slapd -D /etc/dirsrv/slapd-%i -i /var/run/dirsrv/slapd-%i.pid -w /var/run/dirsrv/slapd-%i.startpid (code=exited, status=1/FAILURE)

Feb 27 11:35:13 rhel7ds.brq.redhat.com ns-slapd[728]: [27/Feb/2016:11:35:13 +0100] createprlistensockets - PR_Bind() on 172.25.1.3 port 389 failed: Netscape Portable Runtime error -5986 (Network address not available (in use?).)

Version-Release number of selected component (if applicable):
389-ds-base-1.3.4.0-27.el7_2.x86_64

How reproducible:
often

Steps to Reproduce:
1. Configure nsslapd-listenhost to use external IP address.
2. Disable link on that interface (unplug cable or in case of libvirt VM: virsh domif-setlink $VM_NAME vnetX down)
3. Restart the machine
4. Enable link during the startup when Network Manager waits for the link (that's the tricky part).

Actual results:
dirsrv service fails to start

Expected results:
dirsrv should wait for network.service

This is your proposed fix, right?  Could you please open an upstream ticket https://fedorahosted.org/389/newticket and attach this patch (preferably in the git format patch since it could have your name and comments!) to the ticket?  I'll ack it there.

Thank you so much!

Hi Noriko,

looks like I can't create tickets there:

>TICKET_CREATE privileges are required to perform this operation

I'm attaching patch here. Please replace NNNNN with the ticket number. 

Thank you!

Agh...  This is due to the SPAM on the trac, most accounts are closed... :(  Could you ask Rich to enable back your account for the future use.  In the meantime, I'm going to open an upstream ticket and attach your patch to it.

Thanks, Viktor!

Build tested: 389-ds-base-1.3.5.10-8.el7.x86_64

During the startup dirsrv waits for network. If address is assigned before the
timeout, DS starts up successfully. Otherwise it (rightfully) refuses to start
since there is no address to bind.

Marking as VERIFIED.
