Check the oracledblv status prompt Not available corresponding to lvdiskplay

There is no such oracledblv under / dev/yktoraclevg/.

This can be seen in / dev/yktoarclevg/ only after clvmd is stopped.

I checked a lot of information, but I don't know what's going on.

After checking a service clvmd status, it is found that both the cluster vg and lv display none.

This led me to find the problem.

Directly use the command vgchange-cy yktoracledb

Checking service clvmd status

[root@yktdb1 ~] # service clvmd status

Clvmd (pid 7550) is running...

Clustered Volume Groups: yktoracledb

Active clustered Logical Volumes: oracledblv ysbaklv test

[root@yktdb1 ~] #

You can already see the vg and lv shared by the cluster

Check that the cluster status is normal and the service is started, and then test whether the two nodes can be switched properly.

[root@yktdb1 ~] # clustat
