[Samba] problem with role transfer

[Giuseppe Arvati]

Hello,

samba 4.8.8

yesterday I tried to transfer fsmo roles from APAMFS2 to DC1PIOP but

during transfer of forestdns and domaindns I had errors

ERROR(<type 'exceptions.AttributeError'>): uncaught exception - 'module' 
object has no attribute 'drs_utils'
   File 
"/usr/local/samba/lib64/python2.7/site-packages/samba/netcmd/__init__.py",

but the roles seems to be transferred

[root at dc1piopp netcmd]# samba-tool fsmo show

Today I read emails related to the same problem "[Samba] forestdns fsmo 
role transfer fails - module 'samba' has no attribute 'drs_utils'"

where the problem was a missing import lib in fsmo.py. I added the lib 
and rerun the command but it says

"This DC already has the 'forestdns' FSMO role"

Can I test for possible problems due to errors durind transfer ?

Which kind on commands can I use to verify if all is ok ?


Thnak you

Giuseppe
