桶中的刪除對象，但大小存儲不增加到riak

Question

我設置一個系統組成riak，riak-cs和支柱到服務器，我用s3tool把對象放入riak，但是當我刪除對象時，它通知「文件s3：//桶/對象刪除「，我檢查大小 /var/lib/riak然後它不會增加。雖然，我加入{delete_mode，立即進入}文件/etc/riak/app.config

文件中配置：

[

任何幫助嗎？

Answer 1

了Riak CS也有leeway_seconds設置。目的是保留已刪除對象的數據塊，以允許在刪除命令之前開始下載的較慢客戶端完成下載。默認設置是24小時。這意味着在Riak CS中刪除的對象在24小時過後纔會有資格進行垃圾回收。在此之後，下一次GC運行將從Riak中刪除數據塊，並將其替換爲墓碑。如果將delete_mode設置爲immediate，則Riak墓碑將立即從後端刪除。

但是，Bitcask後端將不會釋放磁盤空間，直到合併操作處理包含舊值的文件。 riak-admin vnode-status命令將顯示每個Bitcask後端中每個數據文件的碎片百分比，死區字節數和總大小。
