@ab-mohamed You can try out this new feature in our development branch now. Please make sure to use the latest rpms for the drbd, hana, netweaver formulas.

@yeoldegrove Unfortunately, the deployment execution was failed.

The DRBD cluster was not created successfully, as shown in the attached deployment output logs.

The monitoring server reported only the default-vmdrbd02 instance as the online node, but there were no configured resource agents, as shown below:

default-vmdrbd02:~ # crm_mon -rnf1
Cluster Summary:
  * Stack: corosync
  * Current DC: default-vmdrbd02 (version 2.0.4+20200616.2deceaa3a-3.12.1-2.0.4+20200616.2deceaa3a) - partition with quorum
  * Last updated: Mon Dec  6 11:24:57 2021
  * Last change:  Mon Dec  6 10:04:39 2021 by root via cibadmin on default-vmdrbd02
  * 1 node configured
  * 0 resource instances configured

Node List:

The DRBD disk was not used:

And there were no created NFS shares.

I am going to share the following files:

  1. terraform.tfvars
  2. The deployment logs
  3. supportconfig from each instance
  4. /var/log directory content from each instance

After fixing the monitoring setup in https://github.com/SUSE/hanadb_exporter/pull/101 and https://github.com/SUSE/ha-sap-terraform-deployments/pull/807 I was able to build a setup with the load-balancer setup enabled (new default).
