特定集合中的损坏索引答案

【问题标题】：Corrupted index in a particular set特定集合中的损坏索引

【问题描述】：

我们遇到了使用辅助键丢失记录的问题。一组即 user 包含以下 bin：name、email、password、role 和 private_token- 在 bin 上有一个辅助键private_token.

关于问题：截至上周，谷歌云中有四个节点。用户集的辅助键工作正常。在上周末，我们创建了一个新节点，现在这个特定的集合在使用辅助键查询它时停止返回任何数据。对于其他所有具有类似配置的集合，它们一直返回正确的值。

用户集的命名空间 n1 正在使用非本地 SSD 存储。

为了解决问题，我们创建了一个新的命名空间，即 test，它存储在内存中。这是一个在 n1 命名空间中失败但在 test 命名空间中成功的脚本：

INSERT INTO test.user (PK, name, email, password, role, private_token) VALUES ('test@test.com', 'Test 1', 'test@test.com', 'password_test_1', 'role_test_1', 'private_token_1')
INSERT INTO test.user (PK, name, email, password, role, private_token) VALUES ('test2@test.com', 'Test 2', 'test2@test.com', 'password_test_2', 'role_test_2', 'private_token_2')
CREATE INDEX user_private_token ON test.user(private_token) STRING


SELECT * FROM test.user WHERE private_token = 'private_token_2'

这是测试命名空间中的输出：

+----------+------------------+-------------------+---------------+-------------------+
| name     | email            | password          | role          | private_token     |
+----------+------------------+-------------------+---------------+-------------------+
| "Test 2" | "test2@test.com" | "password_test_2" | "role_test_2" | "private_token_2" |
+----------+------------------+-------------------+---------------+-------------------+
1 row in set (0.001 secs)

在 n1 命名空间中：

0 rows in set (0.001 secs)

aerospike 版本：

$ dpkg -l | grep aerospike

尝试在 asadm 中进行故障排除：

我怎样才能修复这个集合并再次拥有一个工作索引？

不太可能仍然是一个问题，但操作手册的Managing Indexes 文章包含有关如何修复索引的信息。自您引用的 3.6 版以来，二级索引上也有相当多的work done。
