Re: BDR table level replication questions

I think I spotted the problem today, I am missing a role on node2.

Is there a pointer to or can you provide list of steps to take for the manual cleanup mentioned the log file. I am assuming I just need to remove the relevant entries in the bdr tables just on node2 in my case. Is that correct?
