CRS-2800: Cannot start resource 'ora.asm' as it is already in the INTERMEDIATE state on server ‘RAC02’

　　在安装ORACLE RAC的Grid Infrastructure时，在节点1运行/u01/app/11.2.0/grid/root.sh正常，当在节点2运行/u01/app/11.2.0/grid/root.sh时发生报错：

[root@RAC02 tmp]# /u01/app/11.2./grid/root.sh

　　根据上面报错，可以看到是因为在启动ora.asm磁盘时发生了错误，因此对比两个节点的asm磁盘权限，发现以下问题：

节点1：

[root@RAC01 app]# ls -l /dev/asm*
brw-rw----  oracle oinstall ,  Feb   : /dev/asm-disk1
brw-rw----  oracle oinstall ,  Feb   : /dev/asm-disk2
brw-rw----  oracle oinstall ,  Feb   : /dev/asm-disk3
brw-rw----  oracle oinstall ,  Feb   : /dev/asm-disk4

节点2：

[root@RAC02 app]# ls -l /dev/asm*
brw-rw----.  oracle oinstall ,  Feb   : /dev/asm-disk1
brw-rw----.  oracle oinstall ,  Feb   : /dev/asm-disk2
brw-rw----.  oracle oinstall ,  Feb   : /dev/asm-disk3
brw-rw----.  oracle oinstall ,  Feb   : /dev/asm-disk4

　　从上面可以看到节点2的asm磁盘权限中多了一个‘.’，这里的点是seLinux的附件权限，但是查看seLinux已经处于Premissive，配置文件中已修改为disabled，因此重启服务器，再次查看asm权限，发现‘.’消失，再次执行/u01/app/11.2.0/grid/root.sh脚本，无报错
