Question

我正在尝试将Barman配置为备份。当我做barman check replica时，我会继续：

Server replica:
WAL archive: FAILED (please make sure WAL shipping is setup)
PostgreSQL: OK
superuser: OK
wal_level: OK
directories: OK
retention policy settings: OK
backup maximum age: FAILED (interval provided: 1 day, latest backup age: No available backups)
compression settings: OK
failed backups: OK (there are 0 failed backups)
minimum redundancy requirements: FAILED (have 0 backups, expected at least 2)
ssh: OK (PostgreSQL server)
not in recovery: FAILED (cannot perform exclusive backup on a standby)
archive_mode: OK
archive_command: OK
continuous archiving: OK
archiver errors: OK

我正在使用Postgresql 9.6和barman 2.1;我不确定这个问题可能会有人帮忙吗？这是我的Barman服务器配置：

description = "Database backup"
conninfo = host=<db-ip> user=postgres dbname=db
backup_method = rsync
ssh_command = ssh postgres@<db-ip>
archiver = on

Answer 1

barman check尝试通过声明归档中存在实际内容来确认归档是否已正确设置。但是，WAL段通常只有在填满后才会存档，如果您的服务器处于空闲状态，则永远不会发生这种情况。

要解决这个问题，Barman提供了一个强制段切换的命令，等待已完成的WAL显示，然后立即存档：

barman switch-xlog --force --archive replica

Answer 2

简介

Barman的incoming_wals_directory和Postgresql.conf的archive_command如详细信息here所述不匹配

详细信息

另一个原因是

之间的不匹配

酒保的incoming_wals_directory
Postgresql.conf的archive_command

要检查的Bash实用程序

barman@backup $ barman show-server pg | grep incoming_wals_directory
# output1
# > incoming_wals_directory: /var/lib/barman/pg/incoming

postgres@pg $ cat /etc/postgresql/10/main/postgresql.conf | grep archive_command
# output2
# > archive_command = 'rsync -a  %p  barman@staging:/var/lib/barman/pg/incoming/%f'

我们在：output1和：output2中必须具有相同的路径

使它们匹配，如果它们不匹配，并且不要忘记之后重新启动postgres。

WAL存档：FAILED（请确保WAL装运已设置）
