Exadata磁盘损坏导致磁盘组无法mount恢复（oracle一体机磁盘组异常恢复）

发表于 2023 年 7 月 28 日由惜分飞

Oracle Exadata客户,在换盘过程中,cell节点又一块磁盘损坏,导致datac1磁盘组（该磁盘组是normal方式冗余)无法mount

ERROR: alter diskgroup datac1 mount force

故障原因是由于asm disk 32还已经损坏在换盘过程中(数据没有reblance完成),又损坏了asm disk 39,而这两份磁盘中有数据互为镜像,因此磁盘组无法正常mount起来.

检查cell节点celldisk和griddisk情况，确认底层磁盘损坏

对于这种情况,因为normal冗余的两份数据都有部分丢失,无法直接恢复数据,通过底层磁盘级别恢复(参考以前一次的Oracle exadata故障恢复:Oracle Exadata坏盘导致磁盘组无法mount恢复),然后比较顺利恢复数据,实现业务数据0丢失

SQL> alter datac1 mount;

Diskgroup altered.

SQL> alter diskgroup datac1 check all;

Diskgroup altered.

多套库顺利open成功

在实际恢复过程中由于客户进行了各种尝试,直接新镜像盘然后插入新盘,强制拉磁盘组drop异常disk操作等,导致第一现场发生一些破坏,增加了恢复难道,但是最终通过各种方法弥补,实现了预期的恢复效果(业务数据0丢失)

客户反馈,数据库无法正常启动，通过分析asm的alert日志发现,data磁盘组mount成功之后,没有一会儿自动dismount掉

这里看主要是由于asm 磁盘组需要做COD recovery导致无法正常稳定的mount,主要原因是遭遇到asm disk的逻辑坏块(存储物理上看是ok的,但是实际数据在asm中看是异常的)

对于这类故障处理相对比较容易,通过patch asm，让data磁盘组稳定mount,然后open库,迁移数据,实现数据0丢失,完美恢复

KFED-00322: Invalid content encountered during block traversal: [kfbtTraverseBlock][Invalid OSM block type][][0]

通过kfed分析,该block确实异常,该block主要记录au的分配信息,如果asm 磁盘组的空间不变化,不执行rebalance,一般不会主动访问该block,不访问该block磁盘组也就不会dismount,按照这个解决思路,通过patch解决,让oradata磁盘组不再执行rebalance和分配/回收空间即可一直稳定的mount
