 ##Step 2. Creating the pod with iSCSI persistent storage
 Once you have installed iSCSI initiator and new Kubernetes, you can create a pod based on my example *iscsi.json*. In the pod JSON, you need to provide *targetPortal* (the iSCSI target's **IP** address and *port* if not the default port 3260), target's *iqn*, *lun*, and the type of the filesystem that has been created on the lun, and *readOnly* boolean. 
 
+**Note:** If you have followed the instructions in the links above you
+may have partitioned the device, the iSCSI volume plugin does not
+currently support partitions so format the device as one partition.
+Make sure you have the correct device name then run the following as
+root to format it:
+
+```console
+mkfs.ext4 /dev/<name of device>
+```
+
 Once your pod is created, run it on the Kubernetes master:
 
 ```console
