Aerospike asbackup 命令生成无效命名空间错误

Question

要将 Aerospike 数据库中测试命名空间中的数据备份到当前目录，以下 asbackup 命令会生成无效命名空间错误。

里面有测试命名空间和员工集，记录很少。我可以使用 golang 驱动程序读写记录。 asbackup需要配置吗？

asbackup --host 172.28.128.3:3000 --namespace test  --directory .

错误是：

2020-02-11 16:48:32 UTC [INF] [88270] Starting 100% backup of 172.28.128.3:3000

使用 MacOs 10.15.3； Aerospike 备份实用程序版本 3.2.3； C 客户端版本 4.2.0； docker 2.2.0.3

上的 Aerospike 运行

我会仔细检查您的命名空间拼写/区分大小写...

    $ asbackup --host 172.28.128.3:3000 --namespace test --directory .

这可能会有所帮助，正如我注意到您提到的 docker：https://discuss.aerospike.com/t/invalid-namespace-error/6117

（asbackup 基本上是获取分区映射失败，而且在那篇文章中，是关于不匹配的 mtu）。
