VMware VMFS Datastores

MAAS can configure custom local VMware VMFS Datastore layouts to maximize the usage of your local disks when deploying VMware ESXi. As VMware ESXi requires specific partitions for operating system usage you must first apply the VMFS6 storage layout. This layout creates a VMFS Datastore named datastore1 which uses the disk space left over on the boot disk after the operating system partitions have been applied.

Listing VMFS Datastores

To view all VMFS Datastores on a machine use the ‘vmfs-datastores read’ API call:

maas $PROFILE vmfs-datastores read $SYSTEM_ID
[
    {
        "human_size": "45.8 GB",
        "filesystem": {
            "fstype": "vmfs6",

Viewing a specific datastore

To view a specific VMFS Datastores on a machine use the ‘vmfs-datastore read’ API call:

maas $PROFILE vmfs-datastore read $SYSTEM_ID $VMFS_DATASTORE_ID
{
    "uuid": "fb6fedc2-f711-40de-ab83-77eddc3e19ac",
    "name": "datastore1",
