In this example, you extend the logical file system by allowing it to span to a new partition.
vmkfstools -Z /vmfs/devices/disks/naa.disk_ID_2:1 /vmfs/devices/disks/naa.disk_ID_1:1
The extended file system spans two partitions—naa.disk_ID_1:1
and naa.disk_ID_2:1
. In this example, naa.disk_ID_1:1
is the name of the head partition.
