Hi Nicolas, I would like to take stab at this one, as i had recently worked on a demo of barman. But like Michael Paquier said, it is better to check the information i provide and the situation you are facing with the maintainers of the project. Here is what i found.
The first thing is to check if you can see the replication slot named "barman" created on the target database using the below command. It should return a slot named "barman" with the slot_type as "physical". The "replication slot: OK" line of the check command shows the slot is available, however, please double check if it is true with the below query. select * from pg_replication_slots; Now let us target the line "WAL archive: FAILED", I faced this issue when i had killed the "receive-wal" process and restarted it. First look for the receive-wal process with the ps command ps -ef|grep receive-wal if it is not running then start it up in the background using the command $ barman receive-wal tcgepg96ddm & If the receive-wal process is running but you still face that error in the check command, then I suggest you switch the xlog using the below command. $ barman switch-xlog tcgepg96ddm if the above command fails to switch the xlog, then try to force it with the below command. $ barman switch-xlog --force tcgepg96ddm if you still cannot get it to work, then try to reset the status of the receive-wal process using the --reset option as below. $ barman receive-wal --reset tcgepg96ddm If you can successfully run the above reset command, then try to switch the log file and run the check command again to see if everything looks fine. $ barman switch-xlog tcgepg96ddm Hope that helps, again, these are the steps i had taken to resolve a similar issue. You might still want to get in touch with the project maintainers about the validity of the above commands.
