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.

Fixed In Version: 389-ds-base-1.3.1.2-1.el7
Doc Type: Bug Fix
Doc Text:
Cause: The replication status attribute nsds5beginReplicaRefresh is not correctly set after an initialization is performed against a disabled replication agreement. Consequence: It appears that the replication agreement initialization never finishes. When in fact it never took place. Fix: Return an error when trying to initialize a disabled replication agreement. Result: The replication agreement status attributes contain the correct values.

Description Nathan Kinder 2013-04-08 01:33:00 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47304

Tested in the context of IPA.

I installed two masters. On one master I disabled the replication agreement, then did a full re-init. The re-initialization never completes.

To reproduce:

* ipa-server-install ...
* ipa-replica-prepare ...
* ipa-replica-install ...
* ldapmodify -h replica ... nsds5ReplicaEnabled=off
* ipa-replica-manage re-initialize --from=master

389-ds-base-1.3.0.2-1.fc18.x86_64

The context of this is backup and restore in a replicated environment. I'm looking for a way to pause replication when doing a restore, so that all non-restored masters can get re-initialized from the restored master.
Comment 1 Rich Megginson 2013-10-01 23:27:14 UTC 
moving all ON_QA bugs to MODIFIED in order to add them to the errata (can't add bugs in the ON_QA state to an errata).  When the errata is created, the bugs should be automatically moved back to ON_QA.
Comment 3 Sankar Ramalingam 2013-11-11 10:32:43 UTC 
Disabled one of the consumer from the replication agreement and re-initialized replication agreement to verify whether it hangs. The ldapmodify is exiting with error 53 which is expected. No hangs observed. Hence, marking the bug as Verified.
