ORA-15096: lost disk write detected

文档解释

ORA-15096: lost disk write detected

Cause: A failure either by disk hardware or disk software caused a disk write to to be lost, even though ASM received acknowledgement that the write completed. Alternatively, a clustering hardware failure or a clustering software failure resulted in an ASM instance believing that another ASM instance had crashed, when in fact it was still active.

Action: The disk group is corrupt and cannot be recovered. The disk group must be recreated, and its contents restored from backups.

ORA-15096:这是一个在ASM中对磁盘资源的错误。它通知您,在某次写入磁盘的尝试中,没有读取磁盘,而是检测出了写丢失/丢失的情况。

常见案例

1. 失败的磁盘(执行Scsi勒索后)

2.网络I/O错误(例如连接超时)

3.服务器级网络故障

一般处理方法及步骤

1.确定可能的原因,例如磁盘故障,网络I/O错误等。

2.根据原因找到正确的解决方案,例如更换磁盘,更改服务器网络配置等。

3.以安全模式重启ASM实例。

4.执行bin / dbcnfig.sh检查脚本,其中会进行磁盘群组检查,并修复受影响的存储相关内容。

5.最后,重新启动ASM实例,直至它以正确的方式完成启动。
