我经历了停电杀害所有4个节点在我的卡桑德拉集群。我已经带回了所有的盒子，但是现在当我尝试启动Cassandra（method bin/Cassandra）时，在有一些日志重放之后，我收到以下消息。卡桑德拉例外：指数（1）必须小于尺寸（1）
Exception encountered during startup: index (1) must be less than size (1)
INFO 10:11:00,479 CFS(Keyspace='system', ColumnFamily='peers') liveRatio is 13.10204081632653 (just-counted was 13.10204081632653). calculation took 18ms for 21 columns
（这是刚刚结束，我可以发布更多的消息，如果有帮助）
想出了正在运行只读取一个，我认为我有复制因子3所以所有keyspaces没有其他人就无法工作。
任何想法是为如何做才能挽回这个局面。我有相当多的数据库中的有价值的信息。
卡桑德拉V1.2.6，
的CentOS V6.4
更新：
所有这三个节点死亡似乎提交日志的重播期间要失败。我已经在加粗他们得到的线。我最初的想法是删除该提交日志，并尝试重新启动..但我有点害怕后果！

删除提交日志意味着可能会丢失已写入，但不会刷新到Cassandra的任何数据。这似乎是一个[已知问题]（https://issues.apache.org/jira/browse/CASSANDRA-5905）（[本以及]（https://issues.apache.org/jira/browse/CASSANDRA -5202））。 –
是的，我认为可能是这样。为了将来的参考，我应该在常规基础上刷新节点，即nodetool flush？ – gerrymcdev
