Just checked you smb.conf 


Now i dont know the exact working of : samba-tool domain classicupgrade 

Rowland know all about that but i see some things which might give the problems. 

I’ll have to ask rowland to have a look in this.. 


But i do thinks that the “old samba 3 “ domain was not a domain.

I dont know if that hurts the upgrade. 


Can you check if you have “2 x “ Administrator in your domain? 


And can you run : 

samba-tool dapcmp --filter="whenChanged" ldap://DC1 ldap://DC2  


but im did see what you old samba version was. 

And you didnt tell how big the DB sized are. 

That can really be handy to know.

im not at a computer ti look some things up but im thinking..

dbdir=/usr/local/samba.PDC/dbdirwhat is the size of this dir.

what is the size of the ad db dir on every server now.

i think, something in the old db import causes a resyncwhen you modify something in the db 
so i suggest try monitoring, disk io and cpu, look for buzzy files. 
if we know the files, we know the processes using it. if one all servers the same files are buzy. 
then maybe you found an unknown bug.

the old db came from which  samba version, tell about the old setup, did you use a ldap backend for example?
maybe a post of your old config can be handy also.
