这里报错是一开始asm-d_crs没清除磁盘头信息导致的
======================================== 到这里恢复voting disk失败了 ，下面重新开始再次尝试恢复============
下面恢复时要注意：
crsctl start crs -excl -nocrs 启动后，马上关闭ASM,不要立刻创建create diskgroup CRSVOTEDISK磁盘组，再使用参数启动ASM
不然创建磁盘组时可能会收入如下报错：
例如：（下面的操作看看就好了，直到 ：下面开始再次恢复操作）
[grid@rac1 ~]$ sqlplus / as sysasm

SQL> col PATH for a50

说明没识别出磁盘 ，这里为什么没磁盘现在是搞明白了，因为参数里面根本没设置
SQL> show parameter asm
