Seems like this bug or issue has been around for a decade or more - I've tried setting the reserve to 0 instead of 1 failed node out of 3 already with the same error.
Host cluster cluster.fqdn was not fully refreshed because not all of the nodes could be contacted. Highly available storage and virtual switch information reported for this cluster might be inaccurate.
All of the nodes I can right-click and view the "status" with all green checkmarks. Each node I can access the hardware tab and see all the CPU/RAM/Storage areas without problems and it's all correct and pulling all the information from the cluster. It's obviously speaking to the cluster, and it IS pulling accurate information. But none of my VMs show up, the cluster does not refresh - always get this same error (Warning 13926), and trying to refresh my VMs immediately fails with this error:
Unable to contact the cluster service on the host computer (NODE1.FQDN).
Obviously, the cluster is working - passes validation in the normal Failover cluster manager on each node - and I am not having any issues with the cluster at all - I just wanted to fully integrate this new cluster into SCVMM and start learning more and enjoying the benefits of SCVMM since we have licenses for it.
Anyone have any ideas I can try here?
