SAP HANA Cluster on Suse with Pacemaker

Question

Hi Experts,
I am doing setup for pacemaker cluster for SAP HANA using this article: https://learn.microsoft.com/en-us/azure/virtual-machines/workloads/sap/high-availability-guide-suse-pacemaker#install-the-cluster

Step 13. [2] Add the node to the cluster.
Is failing, as it ask for root user password, instead of using ssh key generated earlier in the steps.

As we all know, there is no root password in Azure Linux VM.

Would you mind testing the steps and advice what is wrong.

I am really fade up reading and going over this article.

Thanks,

Apologies in delayed response on this.

Exchange of keys procedure described in Step 6, 7 and 8 in document needs to be performed using root user.
You need to sudo its user to root and perform steps described in the doc.

Once the exchange of keys is fixed, cluster won’t prompt for password when joining the node.

Node 1- Step 6:

Node 2- Step 7:

Copy content from /root/.ssh/id_rsa.pub from NODE 1 to /root/.ssh/authorized_keys in NODE2.

Node 1- Step 8:

Copy content from /root/.ssh/id_rsa.pub from NODE 2 to /root/.ssh/authorized_keys in NODE1.

Verification: Perform ssh to Node 2. It won’t ask any password.

Hope that helps.
