Hello,
I have been able to restore a backup, disabled samba initially, changed
hostname, and then joined as a DC. It looks as if that was successful and some
data was replicated. I had to manually update some DNS data to get it
operational however. As a test whether user data (my major concern) was
replicated, I disabled the old DCs and ran samba-tool user list, and the result
was as expected. Similarly I can modify folder permissions on a windows system
and that looks fine.
However when I try to start windows Active Directory Users and Groups management
tool, I get the error "Naming information cannot be located because: The
network address is invalid. Contact your system administrator to verify that
your domain is properly configured and is currently online."
Anyone knows what network address is invalid, what to check or where to look?
I also tried to look into the replication issue, but I get the following:
root at banana3:/home/joachim# samba-tool drs replicate
banana1.samba.lindenberg.one banana3.samba.lindenberg.one
dc=samba,dc=lindenberg,dc=one
Replicate from banana3.samba.lindenberg.one to banana1.samba.lindenberg.one was

or in summary, replication between banana1 (actually the new DC, I recycled a
device) and banana3 appears to work, but it does not work with dc1.
Any suggestion what to check/change - short of demoting dc1 and rejoining?
Thanks,
Joachim

Betreff: [Samba] replication not done with missing DC?
Hello,
I am running a total of three DCs with Samba, all running Version 4.3.11-Ubuntu
(two actually the derivate Armbian). Now one of them crashed. Maybe I can
recover the system, maybe I have to restore from a backup, but I know I cannot
just run an older backup but instead should rejoin.
Now before continuing I was checking the consistency of the other two and
figured out, they are not in sync. Some user data I created the last days is
missing.
When I look into log.samba I can find both of the remaining DCs trying to
connect to the missing one, but obviously they don´t try to connect directly.
How can I get them to talk to each other?
Thanks & Best Regards
Joachim
