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 a barman cron entry to start barman receive-wal. That needs to be running before you can execute barman switch-wal and finish your setup. =)


What versions of PostgreSQL and Barman are you using?

Before PG 9.3, there were no WAL files ending in FF, it went from FE to 00.

It seems likely you are using PG < 9.3, but your version of Barman is not expecting that.

  • I'm on PG 9.4 and I believe Barman 2.3. On both the servers PG has been installed on custom locations. How do I ensure that Barman is using the correct installation of PG on both machines? Dec 2, 2017 at 4:56
