11.2 RAC自动启动报错诊断(四)

原创 Linux操作系统 作者:yangtingkun 时间:2011-06-21 23:37:44 1 删除 编辑

一个客户的11.2 RAC for Linux X86-64环境停电后出现了故障,RAC环境无法自动启动。

这一篇介绍重装后出现的新问题。

11.2 RAC自动启动报错诊断(三):http://yangtingkun.itpub.net/post/468/518834

 

 

上次诊断了导致问题的原因在于操作系统级别报了大量的I/O相关的错误,客户最终重建了整个RAC环境。在重装的过程中,I/O问题依然存在,最后配合硬件工程师检查存储发现:存储链路断了一条,且其中一个控制器的关键服务没有启动。

文件解决后,I/O错误没有再次出现,RAC环境也成功搭建,本以为问题圆满解决,没有想到这个RAC环境最近又频繁出现自动重启的现象。

检查alert文件发现错误:

显然是ASM实例出现了故障,导致数据库实例和ASM实例通信中断,检查ASM实例告警信息:

看来又是CLUSTER的问题,导致ASM实例的关闭,继续检查CLUSTER的相关日志:

导致ASM实例关闭的原因是VOTE盘读取超时,而导致超时的原因多半又是I/O相关的问题,继续检查ocssd.log

可以看到,导致问题产生的原因是由于超过阈值20秒没有办法获取VOT盘,导致节点被强制重启。

在同一时刻,操作系统上也出现了I/O和多路径相关的错误。

通过dmesg命令查看操作系统上的错误信息:

[root@Oracle-01 log]# dmesg|grep error

显然导致问题产生的根据还是操作系统和硬件级别上的,看来存储和多路径的问题依然没有彻底解决。
