Zookeeper 节点无法再在生产服务器上加载数据库

我在三个不同的 ubuntu 14.04 节点上运行 3 个 zookeeper 集合。该设置以前运行正常，但现在我注意到 zk1 无法运行。它也无法重新启动：

:/home/www$ sudo /etc/init.d/zookeeper status
 * zookeeper is not running

启动脚本不会重新启动 zookeper，也不会停止它。状态显示它未运行。但是，zk2 和 zk3 正在运行，但它们的启动脚本也显示 zookeeper 未运行，但实际上它正在运行。

这是一个生产服务器，到目前为止 solr 已经运行，但我希望尽快修复此问题，非常感谢您的帮助。

这是日志文件，运行了大量的永久错误。数据库似乎出了问题。前几天我不得不删除 solr 的日志条目，这可能是导致错误的原因。

我现在删除了快照并可以在该节点上重新启动 zookeeper，但是它不会连接到集合但只显示一个节点：

echo stat | nc zk1 2181

答案1

Last transaction was partial. 2016-01-15 16:30:02,677 - ERROR [main:QuorumPeer@453] - Unable to load database on disk

我遇到了同样的问题，它主要发生在磁盘空间已满或 zookeeper 无法写入磁盘时。解决此问题的一种方法是清除 zookeeper 日志（/<base_path>/zookeeper/version-2/）。
