Does 'switch-wal' need any specific port to be open? (ERROR: The WAL file has not been received)

[Saurabh Nanda]

Hi Everyone,

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 ensure 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?

Any help would be appreciated here. I"m completely stumped with this one.

Did you try without the timeout ? , I don't think there is any specific port to be open for switch-wal . Are you getting wal shipped to incoming folder from pg server ?
