ORA-29702: error occurred in Cluster Group Service operation

环境:
OS:Red Hat Linux As4
DB:10.2.0.1

今天发现两个节点上的ASM无法启动,导致数据库无法启动,aert_+ASM1.log 错误信息如下:
Errors in file /u01/app/oracle/admin/+ASM/bdump/+asm1_lmon_19696.trc:
ORA-29702: error occurred in Cluster Group Service operation
LMON: terminating instance due to error 29702

具体查看trc文件,错误信息如下:

该问题估计是ASM磁盘组没有mount导致的,手工启动ASM实例,并mount所以磁盘组,问题解决.
ALTER DISKGROUP ALL MOUNT
