Re: [Samba] replication failing for 4.9.4




so the DC with FSMO is not done first?

dc01 is still running 4.7.7.  No need to restart it.  There is also still a DC03 running 4.7.7.  the only one I've upgraded is DC02.  resolv.conf on DC02 is configured with DC01 as the first remote.  This does not appear to be a DNS issue.
As per recommendation, I am first upgrading the non-fsmo servers (DC01 has all the FSMO roles).
This log line does look suspicous:  


[2018/12/28 15:30:47.371819,  0] ../source4/dsdb/common/util.c:1815(samdb_reference_dn_is_our_ntdsa)
  Failed to find object DC=rvx,DC=is for attribute fsmoRoleOwner - Cannot find DN DC=rvx,DC=is to get attribute fsmoRoleOwner for reference dn: No such Base DN: DC=rvx,DC=is



None of the config has been changed.

Hai, 

DC1, did you reboot it or just restarted services, i advice a reboot. 

Then on DC2. Samba internal DNS by accident? 
If so, stop samba, set log level = 10 
Start it wait 30 sec, stop it. 

Now change the resolv.conf so DC1 is the first contacted. 
and start it again. 

Test again. 

Now im out the office in 15 min, but try this.
Keep these logs, a samba dev may ask for it.
