Expanding a VMFS datastore

Use the IBM Storage Ceph Plugin for vSphere to automate the expansion of capacity for vSphere VMFS datastores.

Before you begin

In the vSphere Client inventory, identify the VMFS datastore that you want to expand and identify the associated storage system and pool in which it resides. Review the available capacity of this pool to ensure that there is sufficient space to store the increased volume capacity.

About this task

This task initiates a workflow that increases the available capacity of the selected VMFS datastore.

Initially, to increase the backing volume this workflow issues a volume expansion command to the underlying storage system for the volume, which is hosting the VMFS datastore.

Second, a storage rescan is initiated on the connected hosts to ensure that all hosts correctly identify the increase in volume capacity.

Finally, the VMFS partition is expanded to take advantage of the additional available capacity and the task complete notification shows in vCenter to report a successful completion

1. Select the VMFS datastore that requires expansion and from the Actions menu (or by right click menu), select IBM Storage.
2. From the IBM Storage Ceph Plugin for vSphere submenu, select Expand VMFS Datastore.
3. Enter a value to increase the datastore by, select the appropriate unit, for example, TB or GB.
4. Review the capacity consumption bar to visualize the updated projected consumption.
5. Click Expand.
6. Monitor the Recent Tasks view in vSphere to confirm the task is completed successfully.
