Richard,

You helped me before in #freeipa, so I appreciate the assistance again.

What version of 389 are you using?
rpm -q 389-ds-base
389-ds-base-1.2.11.15-34.el6_5

Thanks,

Hello all,

First and foremost, a big "thank you!" to the FreeIPA developers for a

Now, to the point!

We're trying to re-provision a previous replica using the standard
documentation via the Red Hat site:


https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Identity_Management_Guide/Setting_up_IPA_Replicas.html

However, we're running into errors during the import process.  The
errors are varied and fail at random steps; there was an issue with
NTP or HTTP or LDAP, etc.  This did not happen when we promoted a
separate node to become a replica.

We had previously removed the replica via `ipa-replica-manage del` and
ensured that no trace of it being a replica existed: removed DNS
records and verified that the host enrollment was not present.  I did
not use the "--force" and "--cleanup" options.

What version of 389 are you using?
rpm -q 389-ds-base

You should remove the unused ruv elements. I'm not sure why they were not cleaned. You may have to use cleanallruv manually.
https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/9.0/html/Administration_Guide/Managing_Replication-Solving_Common_Replication_Conflicts.html#cleanruv

note - use the cleanallruv procedure, not cleanruv.


When I check RUV's against the host in question, there are several.  I
also queried the tombstones against the host and found two entries
which have valid hex time stamps;  coincidentally, out of the 9
tombstone entries, 2 have "nsds50ruv" time stamps.  I'll paste
sanitized output below:

As you can see, the "host-in-question" has many RUV's and of which two
appear to be "active" and two entries which I believe (pardon my
ignorance) possibly correlate with the "active" entries of the
"host-in-question".

Do these two tombstone entries need to be deleted with ldapdelete
before we can re-provision "host-in-question" and add it back as a
replica?

No, you cannot delete tombstones manually. They will be cleaned up at some point by the dirsrv tombstone reap thread, and they should not be interfering with anything.

What is the real problem you have? Did replication stop working? Are you getting error messages?


Thank you,
John DeSantis
