Switch to the Targets tab, select a target to enable MPIO and click Connect . The CSI driver daemon set runs a pod on every node that allows OpenShift Container Platform to mount storage provided by the CSI driver to the node and use it in user workloads (pods) as persistent volumes (PVs). Locking is handled by the NFS service and that allows very efficient concurrent access among multiple clients (like you'd see in a VMWare cluster). Warning ProvisioningFailed 7s (x6 over 38s) org. If your network is 10GbE and configured properly at all points using decent equipment, you can indeed get the same sorts of speeds over iSCSI as you do with an SSD (10GbE == ~1280MB/s, theoretical maximum). Longhorn creates a dedicated storage controller for each block device volume and synchronously replicates the volume across multiple replicas stored on.
