exadata磁盘组不能mount恢复
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：

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.
