I beeilve creating a persistent volume and using that in a namesapce and using that namespace whil creating a tenant should solve this issue. But i am stuck with the error of no memory available

As per the code:
if (memReqSize < minMemReq) {
return {
error: "The requested memory size must be greater than 2Gi",
request: 0,
limit: 0,
};
}
You need 2GB of RAM per node. Since you have 4 nodes, you need 8 GB of RAM for Minio alone. It's likely that you don't have the enough RAM to run this.
