记录19c ASM磁盘掉线触发ORA-59048故障处理

在一套Oracle 19c RAC环境中有ocr/vote所在磁盘组有磁盘offline

这里显示被丢失的磁盘状态处于missing,而且state=FORCING，磁盘名字变为_DROPPED_0002_SYSDG,这里表现出来的是磁盘应该是不可访问,然后asm 自动踢掉该盘,但是没有正常清除元数据.查询磁盘reblance状态

该磁盘组在reblance的过程中由于遭遇了ORA-59048导致无法清除掉异常磁盘元数据.关于ORA-59048的官方解释

SQL> !oerr ora 59048
59048, 0000, "Redundancy could not be restored in group '%0!s'."
// *Cause:  An attempt to restore redundancy during rebalance failed for some
//          user data or ASM metadata due to the presence of dropping or
//          forcing disks.
// *Action: Add back all the disks in DROPPING or FORCING state. If this is an
//          Oracle appliance, also add back all the missing disks.

出现该问题的原因是由于
In 12.1.0.2 ASM and higher releases, it is not allowed to Normal Drop the Failgroup in a Normal/High Redundancy Diskgroup if it lowers the Failgroup count below 3 for Normal Redundancy Diskgroup and below 5 for High Redundancy Diskgroup.Any attempt to force drop Failgroup will not expel the disks completely and leave the disks in “FORCING” state.
解决该问题官方的建议:

查看asm的alert日志确认该磁盘组当时具体状态,最早确实是由于/dev/asm_ocr3这个盘访问报io错误

比较简单的而且安全的做法是客户划分一块新的ocr盘上来,然后udev配置并加入到该磁盘组中即可.但是由于该客户存储没有新空间,只能分析尝试把原盘该加入进来.先确认该盘现在读写是否正常(存储故障已经修复)
1. kfed read 或者dd读取该盘确认正常
2. 由于该盘依旧属于sysdg磁盘组的member,无法直接加入
