Question

由于哪个核心损坏，我遇到了完整的磁盘空间（100％）问题。正如我用Google搜索，我删除了version-2和datalog/version-2的所有快照。

现在/var/zookeeper只有myid个文件和__backup文件夹。

我正在尝试启动zookeeper时遇到错误

请你帮我解决这个问题。

谢谢。

显然你的动物园管理员似乎处于一个不稳定的状态，它试图找到一个丢失的节点。查看zoo.cfg文件，看看您的ZooKeeper的dataDir设置是否一致。

或者这可能是Zookeeper的一个已知问题。 https://issues.apache.org/jira/browse/ZOOKEEPER-1813
