接到朋友求救有客户oracle exadata一体机 的 asm磁盘组无法mount,希望我们提供恢复支持服务
经过分析和了解,大致问题是:磁盘空间已经超容量使用(部分数据不能完成ASM镜像),最近又损坏一块盘,导致asm 磁盘组无法mount。我们分析后,通过重构exadata celldisk数据,将asm 磁盘组 mount成功后,实现五套数据库全部open成功(由于底层磁盘部分数据损坏,导致部分数据访问报错,需要在oracle层面进行处理)。

本次问题的具体分析和处理如下:

根据客户的反馈该磁盘组几乎全部被使用,asmcmd lsdg看到Usable_file_MB已经出现负值.证明该磁盘组本身的normal没有完全存储两份数据,在这样的情况下,继续坏盘会导致部分数据只有一份,因此也就出现了这里的磁盘组无法正常mount成功.

通过底层修复celldisk之后
data磁盘组直接mount成功
