無法啟動 bitcoind - “塊文件之前已被修剪”

我按照此說明安裝了比特幣。

我主要將它與bitcoin-qt -testnet選項一起使用，甚至在測試網中進行了一些交易。我正在使用修剪模式。

現在我想執行bitcoind然後連接bitcoin-cli到它。

但是當我執行以下命令時：bitcoind -testnet，我得到以下輸出：

punnysher@punnysher ~ $ bitcoind -testnet

消息說

2018-11-16T09:16:48Z LoadBlockIndexDB()：塊文件以前已被修剪

2018-11-16T09:16:48Z ：您需要使用 -reindex 重建數據庫以返回未修剪模式。這將重新下載整個區塊鏈。

請使用 -reindex 或 -reindex-chainstate 重新啟動以恢復。

如果你一直在修剪模式下執行，bitcoind 一直在修剪區塊鏈。這意味著它已丟棄數據以節省磁碟空間。

要在非修剪模式下執行，您必須恢復失去的數據。提供的方法是再次下載整個區塊鏈。

唯一明顯的選擇大概是在修剪模式下執行。

是的，你必須重新下載整個區塊鏈，沒有捷徑
