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
