Question

我设置了一个由riak，riak-cs和stanchion组成的系统到服务器中，我使用s3tool将put对象放入riak，但是当我删除对象时，它通知＆＃34;文件s3：//桶/对象已删除＆＃34;，我检查尺寸 / var / lib / riak然后它没有增加。虽然，我将{delete_mode，immediate}添加到文件/etc/riak/app.config

中

文件配置：

任何帮助？

Answer 1

Riak CS也有leeway_seconds设置。目的是保留已删除对象的数据块，以允许在delete命令完成下载之前开始下载的较慢客户端。默认设置为24小时。这意味着在Riak CS中删除的对象在24小时后才有资格进行垃圾回收。在此之后，下一次GC运行将从Riak中删除数据块，并用墓碑替换它们。如果你将delete_mode设置为immediate，那么Riak墓碑将立即从后端删除。

但是，在合并操作处理包含旧值的文件之前，Bitcask后端不会释放磁盘空间。 riak-admin vnode-status命令将显示每个Bitcask后端中每个数据文件的碎片百分比，死字节数和总大小。

删除桶中的对象，但大小存储不会增加到riak
