Can multiple VM Clusters each in own VCN share the same Mount Target
We are limited to 2 Mount Targets (MT) per zone, yet we want to support dozens of clusters per zone, each in their own Virtual Cloud Network. Each cluster needs an NFS mount, which is made available using an Export via MT. However, it seems MTs are tied 1:1 to subnets, which I assume means we can only support 2 clusters per zone since each cluster has 1:1 mapping with a VCN which has a 1:1 mapping with a subnet, which then can only have a 1:1 mapping to MT.
The summary says it all. Currently, we make a new MT for each new cluster (an automated process). But once we try to make a 3rd cluster in a zone, it fails due to quota. OCI declined to issue more quota noting that a single MT can support many NFS mounts. My question is how this can happen in a zone with each cluster on its own VCN? Can a MT be set up to be VCN-independent?
