标签归档:asm disk ext3
再一起asm disk被格式化成ext3文件系统故障恢复
国庆节前夕接到朋友求救电话asm disk被格式化成ext3格式了,具体操作如下
并且把这个分区直接挂载到/目录
由于/被挂载新格式化的控盘,导致asm磁盘组访问其他盘报错

重启系统之后,重试mount 磁盘组

由于sdb(asm disk 8)被格式化,导致data磁盘组无法正常mount.这个客户运气比较好data 磁盘组是normal模式,但是由于mount到/,导致disk 4被强制drop,因此无法mount成功,但是通过一系列处理数据实现完美恢复,0数据丢失
如果磁盘组是外部冗余,请参考:
