Option Description<br />
Use free space Deploys an extent in the remaining free space of the disk. This option is<br />
available only when you are adding an extent.<br />
Use all available partitions Dedicates the entire disk to a single extent. This option is available only when<br />
you are adding an extent and when the disk you are formatting is not blank.<br />
The disk is reformatted, and the datastores and any data that it contains are<br />
erased.<br />
8 Set the capacity for the extent.<br />
The minimum extent size is 1.3GB. By default, the entire free space on the storage device is available.<br />
9 Click Next.<br />
10 Review the proposed layout and the new configuration of your datastore, and click Finish.<br />
What to do next<br />
After you grow an extent in a shared VMFS datastore, refresh the datastore on each host that can access this<br />
datastore, so that the <strong>vSphere</strong> Client can display the correct datastore capacity for all hosts.<br />
Increase VMFS Datastore Capacity in the <strong>vSphere</strong> Web Client<br />
When you need to add virtual machines to a datastore, or when the virtual machines running on a datastore<br />
require more space, you can dynamically increase the capacity of a VMFS datastore.<br />
If a shared datastore has powered on virtual machines and becomes 100% full, you can increase the datastore's<br />
capacity only from the host with which the powered on virtual machines are registered.<br />
Prerequisites<br />
Browse to Datastores in the <strong>vSphere</strong> Web Client navigator. See “Display Datastore Information in the <strong>vSphere</strong><br />
Web Client,” on page 23.<br />
Procedure<br />
1 Select the datastore to grow and click the Increase Datastore Capacity icon.<br />
2 Select a device from the list of storage devices.<br />
Your selection depends on whether an expandable storage device is available.<br />
Option Description<br />
To expand an existing extent Select the device for which the Expandable column reads YES. A storage<br />
device is reported as expandable when it has free space immediately after<br />
the extent.<br />
To add a new extent Select the device for which the Expandable column reads NO.<br />
3 Review the Current Disk Layout to see the available configurations and click Next.<br />
4 Select a configuration option from the bottom panel.<br />
Depending on the current layout of the disk and on your previous selections, the options you see might<br />
vary.<br />
Option Description<br />
Use free space to add new extent Adds the free space on this disk as a new extent.<br />
Use free space to expand existing<br />
extent<br />
Expands an existing extent to a required capacity.<br />
