  • nebula 版本:vesoft/nebula-storaged:v2-nightly
  • 部署方式(分布式 / 单机 / Docker / DBaaS):k8s

操作过pod伸缩,重启 最终show hosts没有一个恢复的

@nextflow 您好, 可以说下怎么操作的吗?
安装的时候是几副本?后来是怎么操作的?伸缩分别成多少副本?

是3副本,因为日志太大了导致磁盘爆了,操作了重新部署,一直没有恢复
后来改成单副本 也是不行

现在pod节点会不断重启

@nextflow metad 服务正常不? show hosts meta 显示正常吗?

show hosts meta;
[ERROR (-8)]: No hosts!

错误日志有条日志,不知道有没有关系
W0413 13:55:29.247143 1 FileBasedClusterIdMan.cpp:46] Open file failed, error No such file or directory

您这个是那个服务的日志?

是storaged服务的

不知道有办法快速迁移数据吗 把数据复制到新的集群上

您重新部署的时候有没有动数据?

能不能贴下 storage1 从启动开始的 log?

请问需要哪个日志 太大了

如果我从3个副本改成一个副本 有办法恢复吗

  1. 您这个 log 等级是不是开的太高了…
  2. 要重启之后的 INFO(手动重启一下)
  3. stderr.log, 重启之后的部分就可以

Q: 如果我从3个副本改成一个副本 有办法恢复吗

没有这功能吧…

首先你这里应该是将三个节点变成一个节点后启动storage的日志吧?
从三个storage变成一个storage,meta的是否有修改成一个meta的地址,有的话,可能clusterid都变了,那么其他storage已经就连不上了,需要删除下 cluster.id 文件,这样storage才能接入。
其次你的meta记录的storage是三个,但是你现在的storage只剩一个,所以storage的日志一直报peer找不到。
目前不支持直接从多个storage伸缩成一个,假如你已经直接这样做了,数据应该是读不了了。
假如你只是恢复服务,你可以把meta的data目录删除,重新启动所有服务,这样应该就可以正常使用。

storage和meta都操作过3个变成1个 应该是clusterid都变了
我现在主要是想恢复数据 哪怕是单个节点的数据也可以 部分数据丢失可以接受
请问这种情况最快速的方案是什么呢
