zookeeper 服务器无法将数据库加载到磁盘上

我们有 3 个节点的 kafka 集群，每个 kafka 都包含 zookeeper 服务器和架构注册表

我们在其中一个 zookeeper 服务器上收到以下错误

[2019-11-12 07:44:20,719] ERROR Unable to load database on disk (org.apache.zookeeper.server.quorum.QuorumPeer)

文件夹下的一些快照文件似乎/opt/confluent/zookeeper/data/version-2已损坏

在文件夹下version-2，我们有以下示例文件

many files as log.3000667b5
many files as snapshot.200014247
one file - acceptedEpoch
one file – currentEpoch

所以问题是——如何启动 zookeeper 服务器

据我所知，我们有两个选择，但我不确定

1）一种选择是将version-2文件夹移动到其他位置version-2_backup 并创建新文件夹 -version-2然后/opt/confluent/zookeeper/data 启动zookeeper服务器并希望快照从其他良好的活动zookeeper服务器复制？

2）第二个选项可能是将version-2文件夹移动到其他位置version-2_backup，创建新文件夹 -version-2 并将所有内容从version-2好机器复制到坏的 zookeeper 服务器version-2 ，但我不确定这是否是正确的选择？
