Maximo Open Forum

Hi all,

We're setting up Maximo Application Suite (MAS) on OpenShift and running into some questions around storage design. Our cluster currently has 3 master nodes and 2 worker nodes.

From what I understand, OCS/ODF (Ceph-based) generally requires at least 3 worker nodes to support internal storage deployment (for quorum and high availability). Since we only have 2 worker nodes, I'm not sure if it's possible to proceed with OCS in a supported way.

I'd like to get feedback from the community on:

• Has anyone successfully deployed OCS/ODF on a 3 master + 2 worker setup? If yes, how did you handle quorum and HA concerns?

• If OCS is not an option, what alternative storage backends would you recommend for MAS in this scenario?

  • NFS provisioner?

  • Other CSI drivers that work well with MAS?

• Are there any known workarounds (even if not supported for production) for running OCS with 2 workers for testing / dev environments?

Any real-world experiences, recommendations, or pointers to best practices would be really helpful.

Thanks in advance!
