LVM故障导致RHCS启动故障
1、故障提示
抓取资源管理日志发现提示如下错误

查看lvdiskplay 对应的oracledblv 状态提示 Not available
在/dev/yktoraclevg/下面竟然没有这个oracledblv
除非把clvmd停止后才这个在/dev/yktoarclevg/里就可以看了
查了好多资料都不知道怎么回事
查到一个service clvmd status 后发现 集群 vg和lv都是显示none
这一下让我找到了问题所在
直接用命令vgchange -cy yktoracledb
在查看service clvmd status
[root@yktdb1 ~]# service clvmd status
clvmd (pid 7550) 正在运行...
Clustered Volume Groups: yktoracledb
Active clustered Logical Volumes: oracledblv ysbaklv test
[root@yktdb1 ~]#
已经可以看见集群共享的vg和lv了
在查看集群状态正常了服务也启动了，然后对这个两个节点测试是否可以正常切换。
[root@yktdb1 ~]# clustat
