Resizing datastores

Resizing a datastore enables you to increase or decrease the storage for your virtual machine files. You might need to change the size of a datastore as your infrastructure requirements change.

If you want VSC to resize the containing volume when it resizes the VMFS datastore, you should not use the Use existing volume option under Storage attributes section when initially provisioning VMFS datastore, but instead let it automatically create a new volume for each datastore.

You can increase or decrease the size of an NFS datastore. You can only increase the size of a VMFS datastore.

  1. From the vSphere ClientHome page, click Hosts and Clusters.
  2. In the navigation pane, select the datacenter that contains the datastore.
  3. Right-click the datastore and select Virtual Storage Console > Resize.
  4. In the Resize dialog box, specify a new size for the datastore, and then click OK.
    You can run the REDISCOVER ALL option in the Storage Systems menu to manually update the storage listing under Storage Systems and dashboard, or wait for the next scheduled refresh.
