Openebs works flawlessly on our stand-alone clusters built with kubeadm.
I even rebuilt one of these working clusters with rancher so I know this set of hosts has zero issues, no network problems, nada.
I’ve tried every supposed workaround I’ve found.
Right now trying to work around where you bind mount the node’s /etc/iscsi and /sbin/iscsiadm into the kubelet container.

Running out of time to include this product in our POC. Rancher started this POC as the leading favorite and hence we are fighting to get this working but simply running out of time and haven’t found any viable support resources.
