tikv 启动报错

foxchan · 2021 年9 月 8 日 09:05

【 TiDB 使用环境】
【背景】物理机新搭建集群
【现象】[ERROR] [server.rs:986] [“failed to init io snooper”] [err_code=KV:Unknown] [err=“"IO snooper is not started due to not compiling with BCC"”]
【部署方式】k8s部署

【TiDB 版本】5.1.1
这种报错有什么影响，怎么解决，是否可以忽略，文件系统是xfs
不存在空间问题，内存也够

可以发一下上下文的日志看看，只看报错可以参考一下这个问答帖子一tikv节点无法启动：报错：failed to init io snoope

reserve-space 默认会占用 5 GB ，导致无法启动，如果只是测试，您可以把这里的参数改为 0.https://docs.pingcap.com/zh/tidb/stable/tikv-configuration-file#reserve-space
如果是正式环境，建议扩容磁盘，按照标准配置安装

发帖截图已经显示了，新盘，1T的空间，才用了19G。硬件除了万兆，都符合。

所以你发的和别人发的帖子解决方式都无法解决。而且4.0 版本没有这个报错。
我猜这个是5.0 版本代码新增的。如果影响不大，我就忽略他继续使用。毕竟这是准备上生产环境的

gengliqi-PingCAP · 2021 年9 月 13 日 05:57

没有影响，这个报错可以忽略，这个功能暂时还未启用，之后会修改。

foxchan · 2021 年9 月 13 日 06:35

好的，因为这个日志是error级别，造成了困惑。感谢回答
