I've been scratching my head to solve the following error, but haven't made much progress:
$ barman switch-wal --force --archive --archive-timeout 180 pg
The WAL file 0000000100000059000000FF has been closed on server 'pg'
Waiting for the WAL file 0000000100000059000000FF from server 'pg' (max: 180 seconds)
ERROR: The WAL file 0000000100000059000000FF has not been received in 180 seconds
I had earlier configured barman on a throwaway VPS and everything worked fine. But when I tried replicating this on our final EC2 instance, I ran into the issue mentioned above. I have ensured the following (even though I don't remember doing this on the VPS):
- SSH from barman => pg is working
- SSH from pg => barman is working
- All firewall rules on 'pg' have been disabled, temporarily
What could be the issue here?
Edit: Adding the output of barman check pg

When you run into a problem like this one, be sure to double-check your logs, the
barman check
command, and make sure you set abarman cron
entry to startbarman receive-wal
. That needs to be running before you can executebarman switch-wal
and finish your setup. =)
