This example extends the logical file system by allowing it to span to a new partition.

vmkfstools -Z /vmfs/devices/disks/vml.vml_ID_2:1
/vmfs/devices/disks/vml.vml_ID_1:1

The extended file system spans two partitions—vml.vml_ID_1:1 and vml.vml_ID_2:2. In this example, vml.vml_ID_1:1 is the name of the head partition.
