  • nebula 版本:v1.1.0

  • 部署方式(分布式 / 单机 / Docker / DBaaS):分布式(172.16.2.62、172.16.2.42)

  • 硬件信息

    • 磁盘(SSD / HDD):SSD
    • CPU、内存信息:32核心、128GB
  • 出问题的 Space 的创建方式:CREATE SPACE IF NOT EXISTS ldbc_snb(PARTITION_NUM = 24, REPLICA_FACTOR = 2)

  • 问题的具体描述
    停掉172.16.2.62上的storaged进程,查询报错:

看一下storage的log

为什么是2啊,一般都是奇数啊

测试资源有限,后续加上

确定是v1.1.0么,这个日志的行数对不上的

看上去是quorum没达到的问题,两节点的raft必须两节点都在线

2的多数派还是2啊。。。没法failover

了解了,多谢。

利用nebula-bench导入数据,storaged出现了fatal错误,导致现在任何GO语句执行失败:

[ERROR (-8)]: Get neighbors failed
