Ah.  I see.  I mixed those up but I see that those would have to be

However, I have been trying to beat some invalid RUV to death for a long
time and I can't seem to kill them.

For example, bellevuenfs has 9 and 16 which are invalid:

[ianh@seattlenfs ~]$ ldapsearch -ZZ -h seattlenfs.bpt.rocks -D
"cn=Directory Manager" -W -b "dc=bpt,dc=rocks"
"(&(objectclass=nstombstone)(nsUniqueId=ffffffff-ffffffff-ffffffff-ffffffff))"

So I try to kill them like so:

and it never finishes.

seattlenfs is the first master, that's the only place I should have to
run this command, right?

right, you need to run it only on one master, but this ease of use can
become the problem.
The cleanallruv task is propagated to all servers in the topology and it
does this based on the replication agreements it finds.
A frequent cause of failure is that replication agreements still exist
pointing to no longer existing servers. It is a bit tedious, but could
you run the following search on ALL
of your current replicas (as directory manager):

ldapsearch ...... -b "cn=config" "objectclass=nsds5replicationagreement"
nsds5replicahost

if you find any agreement where nsds5replicahost is a host no longer
existing or working, delete these agreements.

I have 7 FreeIPA servers, all of which have been in existence in some
form or another since I started.  It used to work great.  I've broken it
now but the hostnames and ip addresses all still exist.  I've
uninstalled and reinstalled them a few times which I think is the source
of my troubles so I tried to straighten out the RUVs and probably messed
that up pretty good

Anyway, now what I THINK I have is

seattlenfs
|-freeipa-sea
   |- freeipa-dal
   |- bellevuenfs
   |- fremontnis
   |- bpt-nyc1-nfs
   |- edinburghnfs

Until I get this squared away I've turned off ipa services on all but
seattlenfs, freeipa-sea and freeipa-dal and am hoping that any password
changes etc. happen on seattlenfs.  I need the other two because they
are my DNS.  The rest I can kind of live without since they are just
local instances living on nfs servers.

Here's the output from that ldap query on all the hosts:

yes, looks like the replication agreements are fine, but the RUVs are not.

In the o=ipaca suffix, there is a reference to bellvuenis:

 [{replica 76
ldap://bellevuenis.bpt.rocks:389} 56f385eb0007004c0000


but this seems to be now bellevuenfs.

In the dc=bpt,dc=rocks replica id 9 is causing the trouble. There aretwo replicaids : 9 and 16 for bellevuenfs, and it causes replicationfailure from edinburgh to freeipa-sea. Looks like replicaid 9 is notpresent in freeipa-sea and edinburgh "thinks" it has to send changes,but can't position in changelog.

You had tried to cleanallruv for rid9, which seemed not to complete, butI don't know what the status is on all servers.

what I would do is

check again the ruvs (the fffff.... tombstone) on all servers,

check if there are still active tasks, try to get rid of them, (butthey can be stubborn), either by trying abort cleanallruv or the hardway, stop the server, check the dse.ldif for existing task attributes inthe replica object and remove them.

then either retry cleanallruv, but without the force option (this makesthe task live until all servers are cleaned, but if replication does notwork this will not happen),or, on each server do individual ruv cleaning (only on the server, notthe cleanallruv task), you can have a look here:http://www.port389.org/docs/389ds/howto/howto-cleanruv.html

I went around and around re-initializing from various servers last night
to try make these go away but it's like whackamole.

What's the best way you can think of to put humpty dumpty back together
again?

Thank you so much for your time.  Come to Tacoma and I will buy you all
the beer.

I'm about to burn everything down and ipa-server-install --uninstall but
I've done that before a couple times and that seems to be what got me
into this mess...

Thank you for your help.

looks like you are searching the nstombstone below "o=ipaca", but you
are cleaning ruvs in "dc=bpt,dc=rocks",

your attrlist_replace error refers to the bpt,rocks backend, so you
should search the tombstone entry ther, then determine which replicaIDs
to remove.

I've followed the procedure in this thread:

https://www.redhat.com/archives/freeipa-users/2016-May/msg00043.html

and found my list of RUV that don't have an existing replica id.

I've tried to remove them like so:

adding new entry "cn=clean 97, cn=cleanallruv, cn=tasks, cn=config"

[root@seattlenfs ianh]# ipa-replica-manage list-clean-ruv

What have I done wrong?

The problem I am trying to solve is that seattlenfs.bpt.rocks sends
updates to all its children, but their changes don't come back because
of these errors:

[23/Aug/2016:00:02:16 -0700] attrlist_replace - attr_replace
(nsslapd-referral,
ldap://seattlenfs.bpt.rocks:389/dc%3Dbpt%2Cdc%3Drocks) failed.

in effect, the replication agreements are one-way.

Any ideas?
