Hello, I swear I have read a couple of old threads. Yet I am not sure if it safe to failback to the old master in case of async replication without base backup.
Considering: I have the latest 9.3 server A: master B: slave B is actively connected to A I shut down A manually with -m fast (it's the default FreeBSD init script setting) I remove the recovery.conf from B I restart B I create a recovery.conf on A I start A I see nothing wrong in the logs I go for a lunch I shut down B I remove the recovery.conf on A I restart A I restore the recovery.conf on B I start B I see nothing wrong in the logs and I see that replication is working Can I say that my data is safe in this case? If the answer is yes, is it safe to do this if there was a power outage on A instead of manual shutdown? Considering that the log says nothing wrong. (Of course if it complains I'd do base backup from B). Thank you, M.
