Hi Adrian,
Thanks for taking the time to reply!
2) Are the logs still available for inspection to see if there where
any
errors thrown?
Yes, and we dug into those. And we also found some indications that
something went wrong.
4) How did you determine the rows where missing?
We were alerted by a bug later that day and found that some rows were
missing in the new primary. We did a compare based on primary key and
found that several tables were missing rows. Before the switch we
unfortunately only checked max(id) and did some counts on tables and
those all checked out. We didn't do a count on all tables...
So to come back at the logs:
We dug a little deeper and we did found ERROR logs around the time we
ran the initial copies. During a period of several hours that day we see
a couple of messages like:
ERROR: requested WAL segment 00000001000001F10000001D has already
been removed
What was being run when the above ERROR was triggered?
Regards,
Lars
