1.起因

使用裸设备在rhas4上9i rac建库遇到如下错误
Errors in file /u01/app/oracle/admin/rac9i/udump/rac9i1_ora_18232.trc:
ORA-00600: internal error code, arguments: [2901], [0], [64000], [], [], [], [], []

2.探查

metalink上用ora-600 工具没有找到任何结果

google 发现有网友说最好建的比裸设备的大小小一点

于是将所有的表空间缩小10M再次建库(上述日志中的system表空间使用的/dev/raw/raw4 建立时为500M修改为490M)
依然到上述位置报同样错误

3.追究

再次检查建立分区的相关记录

Command (m for help): n
First cylinder (91-326, default 91):
Using default value 91
Last cylinder or +size or +sizeM or +sizeK (91-326, default 326): +500M

4.明了

[root@ora9i1 ~]# fdisk -l

其中的/dev/sdb5是system对应的分区
其准确的大小为

497983/1024=486M

所以第二次试用490M的时候依然报错
