MAAS: 3.4.1
https://maas.io/docs/api
POST /MAAS/api/2.0/nodes/{system_id}/raids/: Set up a RAID
Request body (multipart/form-data)
block_devices (string): Optional. Block devices to add to the RAID.
block_devices must be array of strings, for example [‘sda’, ‘sdb’]
I found 2 places of calling class CreateRaidForm
from websocket
form = CreateRaidForm(node=node, data=params)
data = {‘level’: ‘raid-0’, ‘name’: ‘md0’, ‘system_id’: ‘yprmdb’, ‘tags’: [], ‘block_devices’: [3, 4]}
from api
form = CreateRaidForm(machine, data=request.data)
data=<QueryDict: {‘block_devices[0]’: [‘sda’], ‘block_devices[1]’: [‘sdb’], ‘level’: [‘raid-1’], ‘name’: [‘md0’]}>
or
data=<QueryDict: {‘block_devices’: [‘sda’], ‘level’: [‘raid-1’], ‘name’: [‘md0’]}>
