11g r2 使用./deinstall卸载报错，尝试手动卸载

           11.2.0.1使用ASM存储，已经用了一天，发现有些问题，决定卸载后重新安装，但在卸载ASM时报错，网上说要下载单独的卸载包来使用deinstall卸载工具，但我发现其实安装完毕后，安装目录也有deinstall文件。

 

[grid@szmlserver12_32 ~]$ find $ORACLE_HOME -name 'deinstall'
/u01/app/11.2.0/grid/inventory/Templates/deinstall
/u01/app/11.2.0/grid/inventory/Templates/deinstall/deinstall   --查看文件日期是2009年的，说明是安装完毕就有的
/u01/app/11.2.0/grid/deinstall
/u01/app/11.2.0/grid/deinstall/deinstall     --最近时间的

卸载：

[grid@szmlserver12_32 deinstall]$ cd /u01/app/11.2.0/grid/deinstall
[grid@szmlserver12_32 deinstall]$ ./deinstall

没办法，找相关文档手动卸载试试：

用root用户登录

[root@szmlserver12_32 install]# cd /u01/app/11.2.0/grid/crs/install/
[root@szmlserver12_32 install]# ./rootcrs.pl -verbose -deconfig -force -lastnode   --如果是RAC去掉-lastnode ，在最后一个节点这样输入，我是单实例

之后再使用./deinstall就可以自动卸载完成：

[grid@szmlserver12_32 deinstall]$ ./deinstall

再用root登陆运行rm -rf /etc/oraInst.loc即可.

 

再重新安装的过程中，遇到建立磁盘的时候，无法选择磁盘：

原来上图的STATUS都是member，当时没仔细看，一个磁盘都无法勾选，后来意识到应该是之前使用过后，ASM依然可以识别出磁盘头信息，所以：

# fdisk /dev/asm-diske

再查看时无法发现 /dev/asm-diske，里面只剩7块磁盘了，感觉应该是磁盘头信息让ASM无法识别，使用dd命令填充磁盘头前512个字节即可：

# dd if=/dev/zero count=10 bs=512 of=/dev/sde   

 

再启动安装即可发现
