客户多个节点rac,早上反馈说有两个节点实例异常,需要分析原因,查看其中一个节点的数据库alert日志,发现是由于访问1399号文件异常报ORA-01242 ORA-01122等错误,导致实例crash

这个错误是数据库文件访问异常导致,根据经验,出现这种问题一般是由于底层异常导致,查看系统messages日志,发现有硬件磁盘报错

客户进一步分析是由于昨天存储坏了一块盘,然后热备盘顶上了,但是不知道什么原因出现了文件访问异常,可能和当时的rebuild过程有关系.由于客户是rac环境,还有部分剩余节点运行正常,对于异常节点直接启动库成功

节点写入数据报ORA-01187: cannot read from file because it failed verification tests错误
ora-01187
在所有节点通过执行ALTER SYSTEM CHECK DATAFILES,然后所有节点操作正常
