barman-wal-archive 与 -WAL 存档：失败（请确保设置了 WAL 运输）

  • 772

我正在尝试使用“barman-wal-archive”找不到解决问题的位置或如何调试它，无论如何有一个全新的 barman 2.10 并且它是日志：

顺便说一句，当我在酒保服务器上发出 barman-wal-archive 时，它​​会要求输入密码：

[barman@barman-server ~]$ barman-wal-archive --test barman-server postgres-server DUMMY
barman@ldn-postgres-barman's password:

[postgres@postgres-server ~] barman-wal-archive --test barman-server postgres-server DUMMY

这件事是我看到第一个 WAL 被接收，然后整个过程就停留在第一个 WAL 上。并且再次重现相同的错误消息？如何定义缺少哪些权限？

我将 /usr/lib/python2.7/site-packages/* 的完全访问权限授予了酒保服务器上的所有用户。酒保权限似乎是文件，因为 WAL 可以由酒保创建。

我在配置中错过了什么？

试过：

[barman@barman-server ~]$ barman switch-wal --force --archive postgres-server
The WAL file 0000000100000004000000A8 has been closed on server 'postgres-server'

它说 - “未收到”，文件在 wal 目录中，但过程因错误而中断。我们有 4 行“为 postgres-server 处理文件归档中的 xlog 段”是否可以？

更新。我安装了 cifs (samba) 并且酒保想使用它。这是与此处相同的未解决问题：https ://sourceforge.net/p/pgbarman/tickets/80/

postgresql barman

    做到了！cifs 应该像这样安装vers=1.0：

    mount -t cifs //ipaddresofsambashare/barman /var/lib/barman -o username=root,password=superpassword,uid=barman,gid=barman,file_mode=0775,dir_mode=0775,vers=1.0

    其他 2.0、2.1 和 3.0 - 没有帮助。

    不酷，但有效

    注意，如果您尝试恢复/恢复数据库 - 恢复服务器上的所有权限都将与酒保服务器上的权限相同！
