Procedure

Steps to re-install Minio:

1. Un-install Minio using helm in the Management Cluster:

Management cluster

# export KUBECONFIG=/etc/nodelet/airctl-mgmt/certs/admin.kubeconfig
# helm -n minio uninstall minio-tenant
# helm -n minio uninstall minio-operator

1. Install the Minio operator:

Management Cluster

# helm -n minio install minio-operator /opt/pf9/airctl/conf/helm_charts/minio-operator-4.5.1.tgz -f /opt/pf9/airctl/conf/helm_values/minio-operator.template.yml

1. Check if the operator is running on the cluster:

Management cluster

# kubectl get pods -A | grep minio-operator

1. Once operator is running, wait for ~30s to let it initialize. Then run:

Javascript

# helm -n minio install minio-tenant /opt/pf9/airctl/conf/helm_charts/minio-tenant-4.5.1.tgz -f minio_tenant_values.yml

Additional Information

Need to check if there are any other underlying issue causing the pod failures, like etcd latency.
