We have deployed a postgres cluster on Patroni. In which replication is not working, I am also getting an error ‘replication slot does not exist’ . Can anyone please help me with this issue, we are stucked here from a very long time. I am posting my patroni.yml file, if any changes I need to do please suggest:

@sayyed3

checkpoint_timeout: 3

first of all: i’m not familiar with patroni. i wonder about that setting, unit are seconds and the default is 5 minutes. why on earth have you reduce that to 3 seconds? usually we remomend to increase it to, for instance 30 minutes. Is PG itself up and running? What can you find in the logfiles?

Und außerdem ist das hier ein deutschsprachiges Forum.

Its resolved. We just reconfigured the data directory
