Hai,
Question.. 2 DC's.  ( debian stretch samba 4.7.5 ) . DC1 upgraded,  ( DC with FSMO roles) samba-tool dbcheck --fix
samba-tool dbcheck --cross-nc --fix
That fixed on DC1  6 errors.
samba-tool drs showrepl show no error.
login on DC2. upgraded.
samba-tool drs showrepl show no error and is in sync.
samba-tool dbcheck --fix  shows 16 errors
uhm, synced, but not synced.. from DC1,


samba-tool drs replicate DC2 DC1 dc=samdom,dc=example,dc=com
again DC2
samba-tool dbcheck --fix  shows 11 errors
so resync fixed 5 errors.
so i did a
samba-tool drs replicate DC2 DC1 dc=samdom,dc=example,dc=com --full-sync
checked DC2 again, still 11 errors? Rowland, if you have a system with errors, can you check this also.
because if this keeps out of sync its imo a bug in drs replication.
or just run the samba-tool dbcheck also on dc2.
I preffer a correct sync..  ;-)
Anyone any ideas? Greetz, Louis
I think dbcheck detects lower level errors in the ldb database which must be corrected on every dc. I've seent this often in the past with pointer to deleted object for example. As far as i understand ad such (deleted for example) elements do not get replicated but get deleted on each dc once they expired.
