How to manage VMFS datastores

You can manipulate VMFS datastores with the MAAS CLI. Note that VMFS datastores cannot be managed via the MAAS UI.

Create VMFS datastore

A VMware VMFS datastore is created on one or more block devices or partitions.

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

maas $PROFILE vmfs-datastores create $SYSTEM_ID name=$VMFS_NAME block_devices=$BLOCK_ID_1,$BLOCK_ID_2 partitions=$PARTITION_ID_1,$PARTITION_ID_2
{
    "system_id": "b66fn6",
    "devices": [
        {
            "uuid": "b91df576-ba02-4acb-914f-03ba9a2865b7",
            "size": 2814377984,
            "bootable": false,
            "tags": [],
            "device_id": 1,
            "system_id": "b66fn6",
            "type": "partition",
            "used_for": "VMFS extent for datastore42",
            "filesystem": {
                "fstype": "vmfs6",
                "label": null,
                "uuid": "fc374367-a2fb-4e50-9377-768bfe9705b6",
                "mount_point": null,
                "mount_options": null
            },
            "path": "/dev/disk/by-dname/vda-part3",
            "id": 80,
            "resource_uri": "/MAAS/api/2.0/nodes/b66fn6/blockdevices/1/partition/80"
        }
    ],
    "name": "datastore42",
    "filesystem": {
        "fstype": "vmfs6",
        "mount_point": "/vmfs/volumes/datastore42"
    },

}

Edit VMFS datastore

To edit an existing VMFS Datastores on a machine use the ‘vmfs-datastore update’ API call:

maas $PROFILE vmfs-datastore update $SYSTEM_ID $VMFS_ID name=$NEW_VMFS_NAME add_block_devices=$NEW_BLOCK_ID_1,$NEW_BLOCK_ID_2 add_partitions=$NEW_PARTITION_ID_1,$NEW_PARTITION_ID_2 remove_partitions=$EXISTING_PARTITION_ID1,$EXISTING_PARTITION_ID2
