无法启动动物园管理员

Question

由于核心损坏，我遇到了完整磁盘 space(100%) 的问题。正如我在谷歌上搜索的那样，我已经删除了 version-2 和 datalog/version-2 中的所有快照。

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

当我尝试启动 zookeeper 时出现以下错误

你能帮我解决这个问题吗？

谢谢。

显然，您的动物园管理员似乎处于不一致状态，它正在尝试寻找丢失的节点。查看 zoo.cfg 文件以查看您的 ZooKeeper 的 dataDir 设置是否一致。

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