From the information, the problem may be caused by split-brain.

Perform the following operations to solve the problem:
Run the following command on the standby server.
drbdadmsecondary r0
drbdadmdisconnect r0
drbdadm-- --discard-my-data connect r0

Run the following command on the active server.
drbdadmconnect r0

After running the above command, check whether the VMU two-node cluster status is normal.


Hope the answer can help you!

Hi user can you check the license?

 The VMU two-node cluster has no permission on the license.dat file.
 The license.dat file is invalid.
