Question

添加节点以测试扩展然后使用cloudbreak删除该节点后，服务ambari-server不会重新启动。

发布时的错误是：

DB configs consistency check failed. Run "ambari-server start --skip-database-check" to skip. You may try --auto-fix-database flag to attempt to fix issues automatically. If you use this "--skip-database-check" option, do not make any changes to your cluster topology or perform a cluster upgrade until you correct the database consistency issues. See /var/log/ambari-server/ambari-server-check-database.log for more details on the consistency issues.

查看日志并不是说得多。我尝试重新启动postgres，有时它可以工作，就像10次一样（怎么可能？）

Answer 1

我的理由更深入，而不仅仅是重新启动postgres。

我打开了ambari表来查看它：

sudo su - postgres psql ambari -U ambari -W -p 5432 （密码是bigdata）

当我查看表 topology_logical_request ， topology_request 和 topology_hostgroup 时，我看到群集注册了一个删除请求，只有一个添加请求：

ambari=> select * from topology_logical_request;
 id | request_id |                        description
----+------------+-----------------------------------------------------------
  1 |          1 | Logical Request: Provision Cluster 'sentelab-perf'
 62 |         51 | Logical Request: Scale Cluster 'sentelab-perf' (+1 hosts)

检查要删除的ID（通过添加节点操作跟踪所有请求）并开始删除它们（订单事项）：

delete from topology_hostgroup where id = 51;
delete from topology_logical_request where id = 62;
DELETE FROM topology_request WHERE id = 51;

关闭\ q，重新启动ambari-server，它就可以了！

使用cloudbreak删除节点后，Ambari服务器不会重新启动
