Problem background and phenomenon
During the cluster initialization phase, the DBService initialization failed.
Cause Analysis
The Fail to set os semaphore parameter is displayed on the interface. This scenario is caused by the failure of the sysctl -p command in the background. The result is not 0. Generally, the device does not exist in /etc/sysctl.conf.
Solution
Step 1 Log in as the root user to the DBServer node that failed to initialize.
Step 2 Execute the sysctl -p command.
Step 3 Clear the nonexistent device from the "/etc/sysctl.conf" configuration.
Step 4 Re-execute sysctl -p to check if the execution result echo $? returns 0.
Step 5 Uninstall the cluster and reinstall.
