Hi,
It's a typical error for brand new setup. After new backup setup do
$ barman switch-xlog --force --archive testdb

Dear All,
I am trying to use Barman to back up PostgreSQL, which is running in a Podman container. However, I encounter the error "WAL archive: FAILED," as shown below:#barman check testdbI have identified that normally, when the PostgreSQL database is installed on a regular VM (not in a container), the archive_command parameter under postgresql.conf looks like this:
Server testdb:
WAL archive: FAILED (please make sure WAL shipping is set up)
PostgreSQL: OK
superuser: OK
PostgreSQL streaming: OK
wal_level: OK
replication slot: OK
directories: OK
retention policy settings: OK
backup maximum age: OK (no last_backup_maximum_age provided)
compression settings: OK
failed backups: OK (there are 0 failed backups)
minimum redundancy requirements: OK (have 0 backups, expected at least 0)
pg_basebackup: OK
pg_basebackup compatible: OK
pg_basebackup supports tablespaces mapping: OK
pg_receivexlog: OK
pg_receivexlog compatible: OK
receive-wal running: OK
archiver errors: OKarchive_command = 'rsync -a %p barman@barman-backup-server-ip:/data/barman/main-db-server/incoming/%f'However, when PostgreSQL is installed on a Podman container, I cannot use the above archive_command because within the PostgreSQL container, it doesn't understand rsync, ssh, and the barman user. That's why I have to use a normal copy command like:
archive_command = 'cp -i %p /srv/archive/%f'I then mounted this wal-files folder on '/data/barman/main-db-server/incoming/%f'. As a result, all these wal_files have the PostgreSQL ownership and not the barman ownership. The barman user has no privileges to change these wal-files, which is why the WAL archive is marked as FAILED.
Do you know how to solve this issue? do I have to install Barman and PostgreSQL in the same Pod container in order to backup PostgreSQL container? Or is there another solution to this problem?
Thank you for your support in advance.
Best,
Ha
