That's really strange, because AFAIK, DS replication module yells
periodically if it cannot replicate so you should see it on the last
errors log page.
That should not occur. I remember a test case
(https://fedorahosted.org/389/ticket/47788) where a transient error
could conduct to an update being skipped.
Do you have access/errors logs since the missing entry was added.
Also would you dump the RUV on each of the masters (ldapsearch -D
"cn=directory manager" -w xxx -b "<your
suffix>"(&(objectclass=nstombstone)(nsUniqueId=ffffffff-ffffffff-ffffffff-ffffffff))"
Are you able to reproduce this problem ?
I do believe the one master with up-to-date data is a reliable
representation of what the LDAP directory should look like. I ran a
reinitialize command (ipa-replica-manage re-initialize --from
reliable-server.fqdn) on two of the out-of-date masters yesterday
around 4pm
EST. It's now a little after 12pm EST and the "Update in progress"
message is
still scrolling by once a second on both terminals. I'd greatly
appreciate
suggestions about a) how to determine the status of the reinitialize
command
and b) any other ideas about how to resolve this issue and monitor
for it
better in the future. Thanks in advance for your help!
Thierry or Ludwig, any idea?
The replica agreement on the master should say when the total update is
completed. But after 12h it looks very long.
You may monitor the number of sent entries (grep -c
'2.16.840.1.113730.3.5.6' <replica log>/access) to see if it progressing.
If it is not progressing for several minutes, would you get a pstack of
the master .
