1 不能创建acfs文件系统，asmca图形界面如下：

2  参考 11.2 ASMCA displays a disabled (non-selectable) ACFS tab (文档 ID 1593187.1)

官方文档进行处理。

验证ACFS是否安装

[root@racdb1 ~]# cd /u01/app/11.2.0/grid/bin/

[root@racdb1 bin]# ls -ltr acfsdriverstate*

-rwxr-xr-x 1 root oinstall 2792 Oct 21 09:46 acfsdriverstate

[root@racdb1 bin]# ./acfsdriverstate supported

ACFS-9200: Supported

[root@racdb1 bin]# ./acfsdriverstate installed

ACFS-9203: true

检查 acfs 驱动是否被加载，发现为空，即没有加载

[root@racdb1 bin]# /sbin/lsmod |grep oracle

[root@racdb1 bin]#

启动ACFS

[root@racdb1 bin]# ls -ltr acfsload*

-rwxr-xr-x 1 root oinstall 1111 Oct 21 09:46 acfsload

[root@racdb1 bin]# ./acfsload start

再次检查 ACFS模块，发现已经有了

[root@racdb1 bin]#   /sbin/lsmod |grep oracle

oracleacfs           2042042  0

oracleadvm            237414  0

oracleoks             460436  2 oracleacfs,oracleadvm

3 再次查看图形界面，发现好了
