Having a discussion with some devs, concerning a bucardo sync that's not
'behaving'. We have a master-master setup, with one environment - call
it "Y", which is the normally 'active' environment, and environment "Z"
being where we fail over to if the Y environment is unavailable/down etc.
While working on a new inititiative, the developers created a new table,
we'll call it 'cards', in environment Z, while building out the new
service. We are now migrating that server/service back to our "Y"
environment, to conform to our desired active/passive architecture. So
the 'cards' table is desired in both Y and Z, synced.
The devs created the table in Y, populated it with the records from Z
(by hand), then added it to bucardo and brought the sync online.
However, adding or changing records in the table on Y is not reflected
on Z - bucardo simply says there are no conflicts and moves on.
I maintain that bucardo has no way of knowing which records between the
two systems are the 'right' records, because there was no fundamental
starting point, with the Y server having a canonical understanding of
the table and its state. I believe that completely removing and
recreating the empty table in Z will get the sync working properly.
Is that correct?
