Hello, I'm in trouble to configure a DB2 HADR Pacemaker cluster in AWS EC2. No way to run successfully db2cm utility. Here a brief description of what happens:

Env: AWS EC2, Linux RHEL 9.4, Db2 version 11.5.9.0 special_58840

Prb: we are configuring Db2 Pacemaker HADR cluster. The db2cm -create -cluster -domain <domain name> -host <host1> -publicEthernet eth0 -host <host2> -publicEthernet eth0 fails with the error:
Line: 1340 Error running command:
crm configure property stonith-enabled=false

all the prerequisite software have been installed on both hosts;

SELinux has been disabled on both hosts and they have been rebooted;

root and instance owner can run ssh passwordless successfully on the local hosts and remote hosts both for long and short hostnames;

no other ideas how to fix the problem.

Has anyone already encountered the same problem as me? Any ideas or suggestions?

Thanks. Ciao. Roberto.

Hello Roberto,

Run the 'crm' property change failing Command Manually.
Watch for Error or Success Output.
   - If successful, it will return without errors.
   - If it fails, you'll get more detailed output.
Check for any error messages like:
   - crm command not found
   - Unable to connect to the cluster
   - Permission denied.
Additionally, run the Db2 Pacemaker prerequisite checker:

  ./db2prereqPCMK


Thanks
Madhusudan
